abstract: This thesis investigates a tight overpressured Cretaceous carbonate formation in Field A of Mexico. The Cretaceous carbonate was penetrated by well A1 and tested oil successfully during an open-hole test covering interval 5356 to 5515 m (MD) that produced oil of 33 degrees API. Initial pressure was 1050 kg/cm2 at 5,227 m (14,934.51 psi at 17,144 ft) that diminished gradually to 450 kg/cm2 (6,400.5 psi). Oil rates varied between 2,200 and 300 bopd. The observed production decline is not economical, given the depth of the reservoir. Field A has log data from 9 wells and 2 re-entered wells. Well logs have been used to investigate the Cretaceous carbonates using a methodology that includes the evaluation of matrix and fracture porosities with a petrophysical dual-porosity model, water saturation, permeability, capillary pressure, pore throat apertures and rock fabric number. Rock fabric evaluation focuses on determining grainstone, packstone and wackestone-mudstone rocks using a rock fabric number. Pattern recognition in Pickett plots is used as part of the analysis. Well A1 was production-tested. Unfortunately, there were some unplanned shut-ins, but it was observed that the original static pressure of the reservoir was not restored following short flow periods. Buildup periods were evaluated with a modified dual-porosity model with restricted interporosity flow due to partial secondary mineralization in the fractures. The evaluation permitted estimating several parameters of interest, including fracture transmissivity, storativity ratio, skin and the extrapolated pressure (p*). The testing suggests that although natural microfractures are present, they tend to close once the well goes on production. Fracture permeabilities (k2) from well testing are very low, in the order of 0.02 md and tend to decrease during subsequent tests; this indicates the carbonate reservoir is tight and stress-dependent. All the information is integrated for estimating Petroleum Initially in Place (PIIP) and reserves. It is concluded that there is oil potential in the Middle Cretaceous carbonate in Field A, which can be tested with horizontal wells and multi-stage hydraulic fracturing. These types of drilling and completion will be required, given that the results of the study indicate that the Middle Cretaceous carbonate is tight.

abstract: Quantum repeaters are the most promising approach for distributing entanglement over long distances. Recent approaches to develop quantum repeaters involve the use of deterministic entangled photon pair sources. On the other hand heralded entangled photon pair sources have been proposed independently both with parametric down conversion source and single photon sources. We modify the latter scheme to implement it as an on demand entangled photon pair source and analyse its performance considering inefficient detectors, inefficient quantum memories and inefficient single photon sources. We conclude that with the current state of art, generation of high fidelity deterministic entangled photon pairs is possible with moderate efficiency. We then compare the results to the deterministic entangled photon pair source obtainable using parametric down conversion source and conclude that the single photon scheme described in this thesis is more practical for such an implementation.

abstract: Magnetic resonance (MR) imaging is a recently developed technique that allows physicians to get high-quality images of living tissue without harmful radiation. MR images are complicated by phase errors, which cause a real image to become complex. In the standard reconstruction technique, the phase error is simply discarded. It is the purpose of this thesis to show how estimating and then compensating for phase errors can help improve the performance of the reconstruction process. Finding a method of estimating the phase error is the first problem to overcome. Existing algorithms are reviewed and a new algorithm based on polynomial modeling is introduced. The algorithms are test d by applying them to three clinical MR images. The desirable properties of a phase estimate are identified and the output of each algorithm is measured for these properties. The advantages of the new polynomial phase estimate are that it has a smooth shape that has good frequency domain properties and a high immunity to image noise. Its disadvantages are that it does not account for localized phase changes and it does not work on all types of images. Partial Fourier reconstruction is a technique that uses phase correction to reduce the raw data requirements of an image. Four existing algorithms are analyzed, and from this analysis, a new algorithm, based on a finite impulse response (FIR) phase correction, is introduced and then modified. The algorithms are applied to both artificial data with artificial phase estimates and clinical data with the phase estimates acquired from the algorithms above. The overall error introduced by the modified FIR algorithm is only slightly poorer than the best of the existing algorithms. Its advantages are that it executes faster and is better at confining errors to the image region where they occur. The magnitude operation that is normally used before displaying MR images produces undesirable side effects in low signal-to-noise ratio (SNR) images and inversion recovery images. In low SNR images, the magnitude operation reduces the contrast of the image. When the magnitude of an inversion recovery image is taken, the sign of the image is lost and the contrast is reduced. Both of these problems can be overcome by using a phase-corrected real image. When tested on clinical images, the images corrected with the polynomial phase estimate produce the best results in both cases. Modeling is a procedure that attempts to reduce rippling artifacts that appear in severely truncated data sets. By modeling phase-corrected data, the algorithm only requires half the computer resources that it needs for complex image modeling. It is shown that modeling and partial Fourier algorithms can be combined to reconstruct images from very small data sets. An image processing package, developed to implement the algorithms in this the is, is described. The package creates a high-speed, interactive image processing environment. An interface was developed to allow researchers to easily add their own procedures to the package.

abstract: A Variational Multi-Scale formulation was used to generate a high-fidelity simulation of a ducted propeller in a 3D unsteady incompressible Navier-Stokes turbulent flow. The blades were incorporated as moving surfaces via an arbitrary Lagrangian-Eulerian treatment of such equations. The domain features surfaces such as struts, ducts and blades whose boundary layer mesh requirements are relaxed via weak boundary condition enforcement. Good grid convergence is obtained. Validation of the model is done for the thrust with third-party experimental data. A wake study shows insights into the flow. These results showcase the applicability of the formulation to evaluate designs of ducted propellers.

abstract: In our globalized and diverse world, the number of international students in post-secondary institutions is increasing more than ever. While bringing their experiences and ideas to their new settings, these students also learn and change the way they see themselves and the people around them. My project is a case study that examines the transformation of Chinese students’ transnational identities against the backdrop of the internationalisation of higher education (Varghese, 2008). Based on a social constructivism paradigm, the study used a qualitative research approach in order to probe issues lying beneath the surface of behaviours (Cohen, Manion & Morrison, 2018) and investigate six individual cases in significant depth. The study includes two phases of data collection. During the first phase, the data was gathered from two rounds of semi-structured interviews: the first round focused on the participants’ experiences abroad; the second, on their home-visiting experiences. In the second phase, through a complementary data collection method, document review, I explored how the participants positioned their identities on social media by investigating their posts on WeChat, which was ubiquitous in Chinese students’ lives for its wide functional range. My findings were analysed on the racial factor and the six conceptual premises of transnationalism proposed by Vertovec (2009). The study will benefit both higher education staff and faculty members in understanding Chinese students’ transnational identities, while helping Chinese international students see themselves better through the lens of “transnationalism”.

abstract:
Estimates in the literature for within-year retention at 2-year colleges range from 57% to 83.9%. This indicates that a large proportion of students who attend 2-year colleges may not be retained beyond the first semester of their studies. Attrition potentially represents a major loss to the student, to the institution, and to society. With current accountability and funding realities becoming more openly discussed, Canadian colleges may not be able to afford to ignore their high rates of attrition in the future.
The focus of this research was to estimate the rate of within-year retention among a sample of students attending two comprehensive community colleges in western Canada, and to develop a predictive model that identified potential determinants of retention among these students. Retention was examined among the total sample, among the sample from each college separately, and among the sample enrolled in each credential type. Astin’s Input-Environment-Output model was used as the framework for this research. The model purports that institutional outputs such as retention must be evaluated in the context of the original student inputs and ongoing environmental factors. Multivariable logistic regression was used to develop predictive models of college student retention.
The estimated overall retention rate among this sample was 83.6%, although differences were observed by credential type. Among the aggregate sample, two environmental factors - grade point average and credit load - were the strongest predictors of retention once other factors were considered. The predictors of retention differed by credential type.
The results indicate that the greatest gains in retention may be realized by strategies aimed at encouraging full-time enrolment and supporting academic achievement. The results of the current study suggest that sub-groups may exist for whom retention is predicted by unique factors. It is important that retention be examined on an institution-by-institution basis. Enhancing our understanding of Canadian college student retention, and taking action to improve retention, may contribute to Canada’s future prosperity in a knowledge economy.

abstract: Changes in the structure of the BINAP framework were shown to provide improved enantioselectivities in asymmetric reactions. This dissertation describes two novel modifications of the BINAP scaffold and their implications in asymmetric reactions. Two BINAP derivatives containing 3,3'-substituents bound to the binaphthalene core via a C-C bond have been prepared. The syntheses of (S)-3,3 '-bis(phenethyl)BINAP and (S)-3,3 '-bis(phenoxymethyl)-BINAP hinged on the successful ortholithiation and iodine incorporation at the I-position of 2-(diphenylphosphinoyl)-3-phenyethyny 1 naphthalene. Electronically similar (S)-BINAP and (S)-3,3 '-bis(phenethyl)-BINAP were compared in Rh- and Pd-catalyzed asymmetric reactions. It was concluded that levels of asymmetric induction and product enantiosense reversals can be attributed solely to a change in the steric properties of the BINAP ligand used. Isosteric yet electronically different (S)-3,3 '-bis(phenethyl)-, (S)-3,3 '-bis(phenoxymethyl)- and (S)-3,3 '-(OBnhBINAP in the same reactions afforded mixed results. This indicated that the nature of the 3,3 '-substituent, not necessarily the cr-basicity of the ligand, might dictate asymmetric induction and product enantiosense. A series of 3,3 '-disubstituted xy!BINAP derivatives were prepared by combining strategies employed in the syntheses of xy!BINAP and 3,3 '-substituted BIN AP ligands. The use of a naproxen ether-based auxiliary allowed for biaryl axis resolution and access to diastereomeric 3,3 '-disubstituted xy!BINAP derivatives. Auxiliary cleavage and further manipulation of a bisnaphthol intermediate afforded 3,3 '-(OiPr)2-xylBINAP and 3,3 '-(OPiv)2-xylBINAP. 3,3 '-disubstituted xylBINAP derivatives were used in Rh- and Pd-catalyzed asymmetric reactions. The effect of 3 ,3 '-disubstitution and the 3 ,5-dialkyl meta effect are cooperative in the Pd-catalyzed arylation of 2,3-dihydrofuran and the Rh-catalyzed hydrogenation of MAC. The naproxen ether-substituted xylBINAP derivatives outperformed all other 3,3 '-substituted BINAP and xylBINAP ligands, with the naproxen and P-xylyl substituents being necessary for high levels of asymmetric induction. The reversal of product enantiosense observed in Rh-catalyzed hydrogenations upon 3,3'-substitution of the BINAP scaffold was further investigated. The energies of the catalyst-substrate complexes involved in the Rh-catalyzed hydrogenation of MAC obtained from OFT calculations were consistent with an anti-lock-and-key mode of enantioselection. Temperature and pressure studies, as well as quadrant diagram analyses indicate that a change in the kinetics of olefin could be responsible for the enantiosense reversals and high levels of asymmetric induction observed with 3,3 '-disubsituted BINAP and xylBINAP ligands.

abstract: In this thesis, highly conductive 1D and 2D nanomaterials including silver nanowire (AgNW), graphene, and MXene were synthesized and used for charge storage. AgNW with high purity and aspect ratio was incorporated in poly(methyl methacrylate) (PMMA) to fabricate a high performance dielectric material. To improve the dielectric performance of the nanocomposites, a hybrid structure, containing AgNW and MnO2NW, was utilized to not only enhance the dielectric constant but also minimize the dielectric loss. The fabricated AgNW:MnO2NW (2.0:1.0 vol %) hybrid nanocomposite showed a high dielectric constant (64 at 8.2 GHz) and low dielectric loss (0.31 at 8.2 GHz), which were among the best reported values in the literature in the X-band frequency range (8.2–12.4 GHz). This superior dielectric performance of the hybrid nanocomposites was attributed to (i) dimensionality match between the nanofillers, (ii) better dispersion state of AgNW in the presence of MnO2NW, (iii) positioning of ferroelectric MnO2NW in between AgNWs, (iv) barrier role of MnO2NW, and (v) the aligned structure of AgNWs, as nanoelectrodes. In the second phase of this thesis, graphene was synthesized via electrochemical exfoliation of graphite in different inorganic salt electrolytes. Electrochemically exfoliated graphene (EEG) sheets synthesized in this thesis had a good dispersibility in water as well as a high electrical conductivity. This eliminated extra steps to increase conductivity such as reduction of graphene oxide. By utilizing these advantages, polyvinyl alcohol (PVA)/EEG nanocomposites were prepared for dielectric application. The prepared nanocomposites had an aligned structure of co-doped EEG (doped with nitrogen and sulfur) and demonstrated excellent dielectric performance. The aligned 4.0 wt% co-doped EEG in the PVA matrix led to a high dielectric constant (201) and low dielectric loss (0.2) in X-band frequency. Different chemical and structural characteristics of the nanocomposite account for the enhanced dielectric properties: (i) good dispersion of co-doped EEG in the polymer matrix, (ii) enhanced polarization centers in the graphene due to nitrogen/sulfur doping, (iii) aligned co-doped EEG sheets, (iv) functional groups at the surface of EEG as barriers between graphene sheets.  In the third phase of this thesis, a modified minimally intensive layer delamination (MILD) synthesis approach was introduced to synthesize a highly conductive Ti3C2Tx MXene. By utilizing the modified approach, the electrical conductivity was significantly improved to 2.4 ×〖10〗^4 S/cm, five times more than that obtained from traditional MILD approach which is about 5.8 ×〖10〗^3 S/cm. This significant improvement in electrical conductivity was attributed to better quality of the synthesized MXene with the modified approach as well as higher flake sizes. Furthermore, the modified approach enhanced the synthesis aspects such as synthesis yield (up to ⁓ 60%) and MXene colloidal concentration (up to 31 mg/ml). The prepared MXene demonstrated a promising application as a supercapacitor, with a high capacitance of ⁓ 490 F/g at 1 A/g. Our synthesis approach has great potential to be used as the next MXene synthesis (etching) approach since it demonstrates improved synthesis yield, high colloidal concentration, and enhanced electrical conductivity.

abstract: Consistent evidence suggests that the built environment can influence physical activity. However, the extent to which the neighbourhood built environment constrains or amplifies the effectiveness of physical activity interventions is understudied. The aim of this thesis was to investigate the role of the neighbourhood built environment in constraining or facilitating the effectiveness of a 12-week internet-facilitated pedometer-based physical activity intervention (UWALK) among inactive adults. Specifically, this thesis examined the effects of the objectively-measured neighbourhood built environment (i.e., walkability estimated via Walk Score®) and the self-reported (perceived) neighbourhood built environment on adoption of, adherence to the UWALK intervention, and levels of pedometer-measured physical activity. A quasi-experiment was undertaken in Calgary between May 2016 and August 2017 which included 573 inactive adults. Self-reported walkability was positively associated with pedometer-measured physical activity. Walk Score® was not significantly associated with pedometer-measured physical activity. Neither objectively-measured walkability or perceived walkability were significantly associated with UWALK adoption or adherence outcomes. Strategies for targeting neighbourhood perceptions may improve the effectiveness of physical activity interventions.

abstract: In this thesis, Low Temperature Oxidation (LTO) reactions of the Athabasca bitumen were studied through numerical simulation and history matching of In Situ Combustion experiments operated under LTO conditions. A new kinetic model in terms of SARA fractions (Saturates, Aromatics , Resins and Asphaltenes) was presented (Model LTO 1) which was based on the four reaction model proposed by Jia et al. (2003). It was necessary to interpret this model in terms of SARA fractions to make it applicable for numerical simulation. Isothermal semi batch experiments for temperatures ranging from 60°C to 150°C (Adegbesan , 1982) were simulated in STARS (the commercial reservoir simulator developed by CMG) using this new Model LTO 1. Multiple variable analyses on the kinetic parameters of each reaction were performed , to match the experimental concentration profiles. The delay in coke formation observed from previous investigators (Adegbesan , 1982; Millour et al. , 1987) was included in the numerical model. The SARA concentration profiles reported by Adegbesan (1982) for different temperatures were matched with Model LTO 1 tuning the kinetic parameters individually for each temperature. It was not possible to match the concentration profiles for all temperatures when using a single set of kinetic parameters, which reflects the change in the oxidation reaction mechanism during liquid phase oxidation as the temperature increases. Simulation and history matching of the experimental results from a Ramped Temperature Oxidation (RTO) experiment operated under LTO conditions were performed. The heats of reaction generated by the Low Temperature Oxidation reactions were incorporated to the simulation. It was found that the Saturates Burning reaction does not occur under the temperature range of the RTO experiment (T <325 °C) . Modifications of Model LTO 1, based on the chemical nature of LTO, were made to match the results of Athabasca Test No. 44 . This led to an improved kinetic model (Model L TO 2) . Temperature profiles, coke yield , oxygen consumption, carbon oxides production , residual hydrocarbon and front velocity were reproduced with an experimental deviation of less than 15%. These results are acceptable considering that the complex liquid phase oxidation reactions of Athabasca bitumen are represented with a relatively simple set of reactions. The improved Model LTO 2 captures the main changes occurring in the bitumen due to oxidation reactions at low temperature conditions . This model can be readily incorporated into numerical simulations of In Situ Combustion to obtain a more realistic representation of this complex process. This study greatly contributes to the understanding of the Low Temperature Oxidation reactions of heavy oils and bitumens .

abstract: It will be argued that that methodology developed in this thesis, known as ‘ideal law methodology’, provides a better alternative to coherence theories of judicial adjudication in adjudicating hard cases. After framing the discussion within the context of Angelo-American legal theory, hard cases, and stare decisis, coherence theories of judicial adjudication will be presented and shown to suffer from conservatism. This will be argued to create problems both in unjust and just societies. The ideal law methodology, which is adapted from arguments from Robert Alexy, will be then be presented. The ideal law methodology uses narrow reflective equilibrium to determine principles of a political community, and then determines and chooses the decision with the largest weighted aggregate realization of principles. It will be argued that the ideal law methodology presents a better method for determining hard cases than coherence theories of judicial adjudication by being adaptive to the community’s political beliefs and thus avoiding conservatism. A number of objections to the ideal law methodology will then be addressed, both from coherence theories of judicial adjudication and elsewhere.

abstract: This exploratory study explored the trans-generational relationships between 14 families who had backgrounds of family violence on three narrative tasks: Family Story, Critical Life Events: High Point, and Critical Life Events: Low Point. Levels of psychological distress were measured using the Brief Symptom Inventory (BSI) for the mothers and the Behaviour Assessment System for Children (BASC) for the children. Psychological distress in both generations was compared to the narrative constructs of coherence for the mothers, and redemption and contamination for both mothers and children (Baerger & McAdams, 1999; McAdams & Bowman, 2001 ). Story content was also investigated, including the presence of family violence, generational boundary violations and thematic content. Gender differences were also explored. Results indicated that depression and psychoticism negatively impact the ability to generate redemption sequences in parents. For children, symptoms such as conduct problems and internalizing behaviours were also significantly related to the generation of redemption and contamination sequences. In addition, redemption sequences in the low point story were significantly related across generations. Contrary to Bearger and McAdams' (1999) findings there were no significant relationships between psychological distress and narrative coherence. Story content analyses revealed a high proportion of the families shared themes across generations. In addition, it appeared that the boys shared more themes of loss, while the girls were more likely to share interpretive type themes. These findings offer many avenues for future research into the cycle of family violence in a narrative context.

abstract: Cardiac arrest is a major health problem; high-quality cardiopulmonary resuscitation (CPR) is one of the most important determinants of survival and survival with good neurological outcomes of the victims. Despite annual training, healthcare providers struggle to conduct guideline compliant CPR during the management of cardiac arrests. Increased likelihood of survival from cardiac arrest depends upon the integration of medical science, educational efficiency and local implementation (of science and education). There is some evidence to suggest that the use of distributed practice (i.e. separating the training into small portions dispersed over time) and real-time feedback (on compression depth, rate, and recoil) can improve CPR quality in healthcare providers and medical trainees. The aim of this research is to explore the efficacy and cost-effectiveness of distributed CPR training with real-time feedback relative to current CPR training practices. To accomplish this, the following work was completed: (1) designing a randomized trial to compare a new CPR training program incorporating workplace-based distributed CPR practice and real-time feedback with a group receiving conventional Heart and Stroke Foundation of Canada (HSFC) Basic Life Support (BLS) course; (2) describing the key components of, and approaches to economic evaluation in the context of simulation-based medical education; and (3) exploring the cost-effectiveness of distributed training program relative to conventional training to inform the decision whether or not to adopt the new CPR training program. This research shows that (1) workplace-based distributed CPR training significantly improves the acquisition and retention of CPR skills in practicing acute care providers and (2) this training method results in decreased training costs and increased learning outcomes in our local context. This research provides evidence to support the educational efficiency of distributed CPR training and informs the decision on implementation of this educational strategy by addressing the cost-effectiveness. Importantly, this research is the first study that comparing distributed CPR training with conventional training and longitudinally analyzing the CPR performance to address skill retention. Furthermore, this research represents the first economic evaluation studies in resuscitation training.

abstract: Understanding the effects of White femininity on social work practice is a worthy endeavour provided the disproportionate numbers of White women that have built and occupied the professional role of social worker from the origins of colonization to present. Mainstream accounts of social work history narrate the profession to be a pursuit of well-intentioned middle- and upper-class White women, concealing the colonial operations that underpin the formation of social work as a White feminine project. Additionally, this dominant discourse conceals the racial segregation prominent in the field of social work that prevents Indigenous, Black, and other racialized people from gaining entry into the profession. While Whiteness and its effects within social work have been a subject of study, the intersection of gender and Whiteness has been minimally addressed, disregarding significant nuances that inform the relationship between the project of colonization and social work. This thesis study provides a detailed analysis of semi-structured interviews with eight White, woman-identified social workers who have practiced in community-based social work for a minimum of two years in Alberta, Canada. Using Foucauldian discourse analysis and drawing from autoethnographic techniques, I trace the ways the participants perform, witness, and disrupt the dominant discourse of White femininity. The findings illuminate the social work profession's ongoing complicity with its colonial origins, which collude with White femininity and ultimately foster practices steeped in racism. A vital need to disentangle social work from its colonial and racist scripts is emphasized.

abstract: The diffusion rate of wind technologies differs between jurisdictions. This study is a comparative historical analysis of how various political and socio-economic variables have influenced and interacted with one another to affect wind technology diffusion in Alberta and Ontario from 1993-2016. Technology diffusion (investment and capacity), political (institutional frameworks, policies, and government in power), and socio-economic (state-level public discourse and cost to consumers) factors are examined. Developing an understanding of the interaction between the different variables provides insight into the wind technology diffusion process. The exploratory analysis found that the priorities and policies introduced by the government in power are major determinants of the rate of wind technology diffusion in Alberta and Ontario. Socio-economic concerns appear to influence political actions, while the results of government actions and policies affect the state-level public discourse on wind power. Future explanatory analyses may uncover the precise relationship between the variables analyzed.

abstract: The vascular T-type Ca2+ channel, CaV3.2, regulates arterial tone by triggering Ca2+ sparks and activating large conductance Ca2+-activated K+ (BKCa) channels. Despite being an integral element of an arterial feedback loop, little is known of its regulation and how key receptors and signaling pathways use this channel to influence tissue perfusion. This thesis will begin to fill key knowledge gaps, undertaking experiments that progress from individual smooth muscle cells to whole arteries, and which entail the use of patch clamp electrophysiology, Ca2+ imaging, pressure myography, immunohistochemistry, quantitative polymerase chain reaction (qPCR) and computational modeling. In initial work, perforated patch electrophysiology was used in concert with Ca2+ imaging to illustrate the coordinated interplay between CaV3.2 and two other Ca2+ permeable conductances in setting voltage-dependent Ca2+ spark production and BKCa channel activation. A second layer of experiments subsequently revealed that caveolae help couple CaV3.2 to Ca2+ sparks generation by placing this T-type Ca2+ channel in close proximity to its intracellular target, ryanodine receptors (RyR). Disruption of the structural arrangement impaired the ability of CaV3.2 to mediate BKCa-mediated feedback in intact resistance arteries. Final experiments revealed that CaV3.2 channels are targeted by common vasoactive stimuli through unique signaling pathways. Of note, was the ability of Angiotensin II to suppress CaV3.2 channel activity through the generation of reactive oxygen species (ROS) by NADPH oxidase (Nox). In summary, this thesis advances our knowledge of Ca2+ handling in vascular smooth muscle by providing new regulatory insight into CaV3.2, a T-type Ca2+ channel involved in optimizing arterial tone and tissue perfusion.

abstract: Articular cartilage and ligament are soft fibrous connective tissues with apparent viscoelastic behavior. An anisotropic visco-hyperelastic constitutive model for these tissues has been proposed in this study based on the short-term and long-term internal variables. The constitutive model was particularized for both tissues, numerically implemented into the finite element software package ABAQUS and the material parameters were identified using the available experimental data. The constitutive model was able to capture both the short-term and long-term time-dependent response of these tissues with less difficulty in material characterization process. Due to the lack of the desired tensile experimental results on articular cartilage, the mechanical behavior of this tissue was also examined experimentally. The tensile stiffness of articular cartilage was found to be rate-dependent. It has been shown by numerical simulations that the strain-rate dependent tensile stiffness of collagen fibers can also contribute to the highly rate-dependent compressive response of articular cartilage, besides the fluid-driven viscoelasticity.

abstract: The production of word stress in a second language (L2) is one area of difficulty for language learners. Previous studies have shown that correct word stress may be more important for the comprehensibility of non-native speech than grammatical accuracy. Studies indicate that incorrect stress patterns in an L2 are mainly due to transfer from learners’ first language (L1). This thesis examines the effect of training on the ability of English native speakers who are beginner-level learners of German to produce stress patterns in words from three distinct categories: native German words; German-English cognate words; and words with unstressed suffixes. The results reveal that training improves learners’ production of German word stress and raises learners’ awareness. Participants were more accurate in their production of native German words and those with unstressed suffixes than they were in their production of cognates. The results have implications for vocabulary teaching in L2 classrooms.

abstract: This study has two distinct objectives. It examines public consultation in environmental issues in Canada during the 1960's and 1970's. The information learned after completion of the first objective is then used to make an assessment and analysis of the Environment Conservation Authority of Alberta 1970-1977. The Authority was an environmental advisory council at the provincial level. This study compares the Authority to other environmental advisory bodies created by Canadian governments between 1970 and 1975. Although all were created to give advice on environmental matters, great diversity was found among them. In a matrix, seven benchmarks were used for advisory body comparison. These were: 1) membership 2) functions 3) public hearings 4) budget 5) staff - 6) publications 7) chairmen. This study shows the Authority was created in 1970 in apparent response to: 1) a government losing voter support 2) a concerned public 3) a recommendation from an advisory body 4) the interest of the Minister of Health. The 1972 and 1977 amendments to the Environment Conservation Act, 1970, changed the Authority from an independent body to an advisory body placed under the Minister of Environment. This new body was called the Environment Council of Alberta. The reasons for these structural changes are believed to be in the interests of efficiency, the desire to eliminate conflicts between the Authority and government departments and agencies, and the lack of need for an independent ombudsman type environmental agency. The Environment Conservation Act, 19?0, reveals a broad mandate for the Authority allowing it to become an environmental advocate. The legislation allowed the Authority to investigate and write reports, to hold public . hearings, to appoint public advisory committees, maintain an information distribution system, to request information and assistance from civil servants, to have corporate status, and to report directly to the Lieutenant Governor in Council. The Authority's performance as a vehicle for public consultation is assessed. Major conclusions reached are: 1) The Authority's public hearings were both accessible and 2) educational. While the Authority's final report and recommendations from public hearings included public input, the Authority members tried to balance public concern with tech no logical facts. 3) Four government decisions are examined to evaluate the amount of input Authority recommendations may have had on those decisions. The evaluation reveals that the authority influenced three of the four decisions although the degree of 4) influence was not always clear. Authority public advisory committees (PAC) had a broad membership from Alberta interest groups. Membership on PAC provided environmental educational opportunities. PAC's study groups might have been more productive with better organization. PAC's writing, research and use of the resolution could also have been improved.

abstract: This study proposes a design strategy for the redevelopment of the "East Village", a deteriorated area of Calgary's inner city, as a residential neighbourhood. Using eighteen architectural drawings, a conceptual neighbourhood site plan is presented and the schematic design of a mixed-use commercial and residential building - developed to illustrate the overall design principles. The accompanying document discusses these principles and their derivation from an investigation of the North American phenomenon of downtown rejuvenation as well as of the idea of the inner city "neighbourhood", specifically in the Calgary context. An historical overview of multiple family and mixed-use building types and a review of local precedents provides additional inspiration for the design decisions. This information, together with careful analysis of the site itself and of its existing and projected population, results in a design which is intended to encourage the evolution of an intimately scaled residential quarter housing a diversity of uses and users. The proposed building typopology is street- oriented and block-edging, and the site plan emphasizes the creation of a defined public realm and the provision of a number of key community amenities. The bibliography list works on urban design . and the history, theory and behavioral and social aspects of multiple family housing design.

abstract: The reliability of a navigation system is important in support of applications from self-driving cars to smartphones, especially for safety-critical and liability-critical applications which require stringent reliability requirements. In recent years, there is an increasing demand for global navigation satellite system (GNSS) integrity monitoring of precise positioning. Due to the features of fast response, strong autonomy and low-cost, user level GNSS integrity monitoring is an effective way to assess the reliability of GNSS positioning systems. It makes use of the measurements redundancy to check the statistical consistency of measurements and provide timely alarms. GNSS measurement noises are typically assumed to be uncorrelated Gaussian white noises in KF for GNSS integrity monitoring. However, this assumption does not hold in practical applications because GNSS observations can be contaminated by hardware noise, multipath, and unmodeled errors, resulting in correlated noises. To tackle the above limitations, an algorithm of user level GNSS integrity monitoring is proposed, which considers temporally correlated measurement noise with an application to real-time kinematic (RTK) positioning. An approach based on colored Kalman filter (CKF) is presented which considers measurement time correlation by a first-order autoregressive model and rebuilds a new measurement model for the CKF. The state variance matrix obtained by the CKF can accurately reflect the realistic position error, while the estimate of the standard Kalman filter is found to be overly optimistic. Then, by considering colored noises in standard KF, an algorithm of enhanced fault detection and exclusion is developed and investigated. This study examined and analyzed the CKF-based fault detection test, a fault identification test, a minimum detectable bias (MDB), error distribution, and positioning results. The CKF-based FDE can obtain realistic statistical information to improve integrity monitoring reliability by reducing false alarm rates. A new method of calculating protection level in the position domain is developed, based on a linear KF by modeling measurement time-correlated colored noise that provides a more realistic protection level in the position domain.

abstract:
The purpose of this study was to compare the academic and emotional-social performances of Grade VII and VIII pupils from single-parent and normal-family homes in one Calgary Junior High School. In all, 16 male and 21 female students were identified in Grade VII, and 20 male and 21 female in Grade VIII, as coming from homes with a single parent. These students were paired with normal-family classmates fo the same sex selected by random from the class list. For these students, data were collected involved academic aptitude, year end subject performance, overall academic average, and a variety of emotional-social factors including absenteeism, misdemeanors, in and out of school activites, and working parents in the home. The results of testing nine hypotheses revealed that, for the most part, no significant differences were found between the overall group performances of the pupils from singles and normal-parent homes. However, and the Grade VIII level, a number of instances were found in which the variability of the single-parent pupils was significantly greater than that of the normal-family pupils. This particular finding was not noted anywhere in the literature. For the emotional-social variables in general, Grade VII single-parent females had a higher rate of absenteeism than normal-family females, while the latter participated in significantly more out of school activities. There were no significant differences between Grade VII boys from either group. At Grade VIII, differences were found with single-parent pupils having a significantly greater number of misdemeanors, and single-parent girls more out of school activities. Single-parent homes had proportionately more working mothers than did normal-family homes. Notwithstanding, over half the mothers in the normal-family group worked.
In general, the findings of this study do not differ markedly from those reported in the research literature. However, the one area that seemed devoid of reference was that of the greater variability of the single-parent pupil sample, particularly at the Grade VIII level,
It was suggested that, as a hypothesis for future study, the effect of the individual family unit has a differential effect on the pupils which would account for the increased variability but which would not be revealed in the overall group performance.

subject: Engineering--Chemical Engineering--Petroleum Thermal Recovery Upgrading Nanocatalysts In-Situ transport

abstract:
Thermal methods are extensively used to extract heavy oil and bitumen with reasonable recovery percentages to compensate for the light oil production decline in recent years. In addition, new technologies are tested to increase the value of the produced liquids. Nanoparticles technology is emerging as a new alternate technology for enhancing the upgrading and recovery processes of heavy oil. Ultra-dispersed nanocatalysts can be injected into the reservoir along with hydrogen to enhance both the upgrading and recovery of heavy oil. Nanocatalysts can be introduced into the reservoir at a typical SAGD configuration (in the area between injector and producer) with the desired residence time to produce higher quality products with enhanced heavy oil recovery. However, before applying these nanocatalysts in the field and testing their performance, their transport behavior inside the porous media and catalytic activity towards heavy oil upgrading and subsequently recovery enhancement has to be determined.
In this study, a pilot plant unit was built in-house to investigate the performance of multi-metallic nanoparticles in an oil sand packed bed column at high pressure and temperature conditions. Results showed that nanoparticles could be controllably delivered inside the medium with a meager influence on the medium permeability. In addition, deposition of the nanoparticles mainly occurs at the entrance of injection zone and rapidly decreases across the reaction zone.
Moreover, effect of different hot fluid injection scenarios on recovery enhancement has been evaluated in presence and absence of tri-metallic nanocatalysts. Comparing the

recovery curves show effectiveness of nanocatalysts on recovery enhancement. In addition, presence of nanocatalysts inside the porous media along with hydrogen enhanced the quality of produced liquids by reducing the hydrocarbon residue and micro carbon content. Furthermore, significant enhancement of liquid viscosity and API gravity was achieved. In the other side, using the nanocatalysts enhanced the hydrocracking reactions by reducing coke formation as well as reduction of carbon dioxide emission, which reduces the environmental impact of nanocatalysts on the in-situ upgrading processes.

abstract: In this case study, the relationship between middle school student engagement, motivation and development of 21st century competencies through a 3D virtual online digital game “Quest Atlantis” was examined.  Data collection included surveys, focus groups interviews, and classroom observations.  Participants were 12 to 13 years old grade 7 students and their classroom teacher.  This research found that seventh grade students were motivated, were engaged and displayed 21st century competencies during game play in the Quest Atlantis environment.  Quest Atlantis provided students with an interactive, technology enabled learning environment in which to engage with Mathematics concepts of statistics that was facilitated by the teacher who provided support and guidance.  No significant gender differences in terms of performance in statistics were found.  Findings from this study can enrich our understanding about the use of digital game based learning for learning Mathematics in schools.

abstract: The voter turnout of Canadian youth ages 18 to 34 is estimated to be 20% lower than those born between 1945 and 1959. Young adults were more than twice as likely to cast a ballot during the first election in which they were eligible in the 1960s when compared with 2004. Low youth voter turnout is concerning because electoral participation is an indicator of the legitimacy and health of democratic systems. Further, voting and abstention behaviours are habit forming, which means citizens who begin adulthood as non-voters are likely to stay that way. While a number of best and promising practices to improve youth voter turnout have been identified, no central means for evaluating the implementation of these practices in Canadian municipal government elections currently exists. This thesis describes the design process for the Youth Electoral Audit, an audit methodology intended to fill this gap. Apathy is Boring (AiB), a Canadian non-governmental organization, conducted a pilot Youth Electoral Audit during the 2013 municipal election in Grande Prairie, Alberta. The Youth Electoral Audit was found to be a practical methodology for evaluating Canadian municipal election practices and facilitating concrete recommendations for improving youth electoral participation.

abstract: This thesis presents the development of a creative, cross-curricular project series using the CDIO framework for engineering education to integrate engineering concepts and the Canadian Engineering Accreditation Board graduate attributes.  The work in this thesis was targeted towards fifth grade students and their teachers, adapting the CDIO process to create an electrical engineering curriculum appropriate for elementary school, called Exploring Electrical Engineering.  As studies show that students begin to lose interest in the domains of science, technology, mathematics and engineering during grades 4/5/6, this work also demonstrates how creative, hands-on projects and positive role models improve the perceptions that grade five students have towards engineering, and towards their consideration of engineering as a future career path.  Through these contributions, the creative, cross-curricular CDIO-based Exploring Electrical Engineering program is demonstrated to have positive effects on young students while introducing them to engineering concepts and attributes.

abstract: The association between peer harassment and academic achievement was examined in relation to individual, parent and teacher factors. The sample consisted of 4,293 adolescents aged 12-15 years drawn from the National Longitudinal Survey of Children and Youth (NLSCY), which is a national stratified sample of households across all provinces in Canada. To analyze the data, numerous variables in the 1'-JLSCY \Vere correlated with harassment and achievement. Gender comparisons using analyses of variance showed that male and female students experience similar rates of harassment. In addition, achievement levels were found to be similar for male and female students in the areas of Language Arts and Math. Latent constructs were derived from measured variables and a latent variable path analysis was conducted to test the model of harassment and achievement. Results showed that the data fit the model well: x2 (63) = 1196.72, p < .001 with a residual error of .03, and comparative fit index of .92. These results suggest that adolescents who are harassed by their peers are at risk for experiencing poor school achievement if they exhibit disruptive behavior problems, as well as have parents who provide little nurturance and show rejection, and whose teachers provide little support. Limitations of the current study and directions for future research are discussed. Finally, this paper concludes with an overview of the implications of the findings for school psychologists.

Game Theory

abstract:
Privacy protection appears as a fundamental concern when personal data is collected, stored, and published. Several privacy protection methods have been proposed to address privacy issues in private datasets. Each method has at least one parameter to adjust the guaranteed level of privacy protection. As the privacy protection level increases, the dataset loses more
information utility due to further application of data manipulation methods and/or access restriction rules. Consequently, balancing the trade ff between privacy and utility is a crucial step and so far no systematic mechanism exists to provide directions on how to establish values for privacy parameters such that a balanced privacy/utility tradeff is induced.
A balanced privacy/utility tradeoff  can be described as a level on which the  stakeholders of data reach a consensus (in the sense that no single party would be wiling to act diff erently to change the agreed upon level). Game theory provides a natural solution to  finding such balanced tradeoff s. In this thesis, we capture the essence of establishing balancing values for privacy parameters as an extensive-form game with incomplete and imperfect information. A
high-level step-by-step guideline is provided on how to solve the generic game. We instantiate the generic game model for three different privacy protection methods and analytically solve each game. The games' solutions are further simulated for sample problem settings to study the effects of various problem parameters on the balancing values of privacy parameters.
The game model and its solution contribute to the  fulfillment of our objective of establishing balancing values for privacy parameters (of a chosen privacy protection method). In addition to our main objective, the proposed game model can be consulted to choose the most pro fitable privacy protection method based on the problem requirements. Benchmarking frameworks can also benefi t from our game solutions by using the balancing privacy parameter values as the reference points for the comparisons between different privacy protection methods. We believe that a first step towards improving the data collection and privacy protection procedures is to understand how much privacy is currently sacrificed to achieve information utility (at the steady states). The game-based solution provided in this thesis promotes a deeper understanding of how privacy and utility reach a balanced tradeoff
within the current privacy protection  methods.

abstract: Electronic devices radiate harmful electromagnetic (EM) waves, which cause EM pollution. We need to shield EM pollution to protect human health and to ensure efficiency of electronic devices. Conductive polymer blend nanocomposite is a potential option to mitigate the challenges associated with commercially-used metal shields. This work aims to attain improved electrical conductivity, electromagnetic interference shielding effectiveness (EMI SE) and dielectric property in immiscible polymer blend nanocomposites. In chapter 4, we have reported three strategies to mix 3 wt % multi-walled carbon nanotube (MWCNT) in five blend compositions of polystyrene (PS)/poly (vinylidene fluoride) (PVDF) blend system. In chapter 5, six techniques are mentioned to mix 2.7 vol % MWCNT in three compositions of PS/poly (methyl methacrylate) (PMMA) blend. Mixing strategy influences filler localization and dispersion. Consequently, we see variations in electrical conductivity, EMI SE and dielectric properties in the blend nanocomposites. The strategy of premixing 3 wt % MWCNT with PS phase has attained 19 dB EMI SE (commercially-significant value) in 1 mm thick PS/PVDF (70:30) blend nanocomposite at a much lower cost than PVDF/MWCNT nanocomposite, reported in chapter 4. Moreover, EMI SE and complex permittivity are found to show a linear correlation (R2 ≥ 0.94). This observation is valid for all the processing techniques and blend compositions, explored in PS/PVDF/MWCNT system. This finding shows the significance of dielectric parameters to attain improved EMI SE in immiscible polymer blend nanocomposite. It has been reported in chapter 5 that one-step solution mixing technique exhibits more than 20 dB EMI SE in 0.8 mm thick samples of PS/PMMA (20:80) and (80:20) nanocomposites, containing 2.7 vol % MWCNT.EMI SE of nanocomposites is observed to increase with sample thickness. This increment is higher in blend nanocomposites than in single polymer/MWCNT nanocomposites. Improved EMI SE in immiscible blend nanocomposites is attributed to selective localization-assisted interphase scattering and better dispersion-promoted intertube scattering of incident EM wave. However, only intertube scattering is active in single polymer/MWCNT nanocomposite. This thesis provides detailed information about the effect of processing techniques and blend compositions on nanofiller localization, dispersion and finally electrical properties of immiscible polymer blend nanocomposites.

abstract: The INhibitor of Growth (ING) proteins are type II tumour suppressors that regulate epigenetic state and transcription by recruiting various chromatin-modifying complexes to chromatin. INGs are involved in multiple cellular processes such as DNA repair, apoptosis and cellular senescence. In this study, we investigated the potential role of ING1 in inhibiting the epithelial-mesenchymal transition (EMT) program that suppresses cancer metastasis and identifies the mechanism of how ING1 regulates gene transcription, as well as its clinical implication in epithelial ovarian cancer. Our analyses revealed that ING1 epigenetically regulates the transcription machinery of the EMT program through binding to the promoter region of Twist1, the critical gene encoding transcription factor (TF) that induce EMT. Subsequently, ING1 promoted the expression of epithelial cell markers, including E-cadherin, while suppressing the expression of mesenchymal markers such as N-cadherin. ING1 antagonized TGF-β or EGF induced EMT and inhibited cancer cell invasion and migration in a Twist1-dependent manner. Integration of ChIP-seq and RNA-seq data revealed the overall genomic binding characteristics of ING1 and its candidate target genes. Gene ontology (GO) and pathway analyses indicated that the genes targeted by ING1 were involved in diverse physiological processes and pathways, mostly associated with the EMT program. The bioinformatical analysis revealed the ING1 binding motif sequence, showing that ING1 recognized target genes through the TEAD family of transcription factors and their co-factor, YAP1, to further influence gene expression. Lastly, we found that high ING1 protein expression was associated with p16 and ARID1A levels and predicted better DSS in ovarian clear cell carcinoma (OCCC). Our data also suggested that high ING1/low N-cadherin expression predicts favourable disease-specific survival (DSS) in epithelial ovarian cancer. These data provide evidence that as a tumour suppressor, ING1 can impact ovarian cancer development through modulating the EMT process and play an essential role in regulating ovarian cancer chemoresistance. In summary, by downregulating the EMT-TF expression and hence and EMT program, ING1 suppresses tumour cell invasion and cancer metastasis. Global genomic profiling revealed new insights into ING1 biology and provided justification for further exploring ING1 functions. This study has also provided critical pre-clinical data that could help establish ING1 as a prognostic and therapeutic agent for ovarian cancer.

abstract: Individuals who sustain an intra-articular knee injury are at a high risk of developing post-traumatic knee osteoarthritis (PTOA) 10-20 years later. Compensatory activation patterns of knee muscles in response to the trauma may persist past the acute injury phase and result in abnormal mechanical loading and subsequent osteoarthritis of the knee. This dissertation aimed to use surface electromyography (sEMG) to explore abnormal leg muscle activation patterns and their possible involvement in PTOA development in individuals who suffered a previous knee injury 3-12 years ago. The first part of this thesis presents methodological investigations related to two sEMG-based assessments of knee muscle activation strategies. It was shown that 1) sEMG amplitude-based co-contraction indices during gait exhibit poor between-day reliability and 2) the magnitude of intermuscular coherence strongly depends on the configuration and alignment of the sEMG electrodes. Building on the methodological findings, the second part of this thesis investigated the association between a previous knee injury and leg muscle activation during walking and squatting while considering the influence of sex. Sex-specific abnormalities in quadricep and hamstring muscle activation patterns were present for the affected leg in individuals more than three years after a previous knee injury. Altered quadricep and hamstring muscle activation may result in abnormal movement and loading of the knee joint and thus be linked to mechanical risk factors for PTOA development. This dissertation could not provide evidence, however, that altered thigh muscle activation was associated with more self-reported knee pain or symptoms indicative of PTOA development. From a methodological perspective, the poor reliability of current sEMG-based markers for abnormal muscle activation may lower the sensitivity to detect associations with risk factors for PTOA. From a conceptual perspective, the development of PTOA is not solely based on joint mechanics but depends on the interplay between mechanical, biological, and structural abnormalities of the joint following a knee injury. Therefore, the pathway to PTOA is likely unique to each individual such that a consistent association between abnormal muscle activation following a knee injury and PTOA risk may not exist.

abstract:
In this research, we propose an agent-based semantic search system supported by ontological concept learning and contents annotation. Our system consists of a group of multi-agent systems (MASs), each controlling a repository of structured and unstructured
documents. Each repository has its own concept hierarchy, i.e. ontology. . Each MAS consists of a group of agents, each with its own responsibilities and an assigned tasks to perform. All agents in each MAS cooperate with each other to perform more general tasks. Agents of different MASs communicate with each other by developing a common understanding of concepts used during communication. Agents communicate with each other via a social network. Strengths of ties between agents in the social network represent how close/far two agents are to each other.
In our system, there are two major modules: a semantic search module and a concept learning module. In the semantic search module, MASs cooperate with each other to perform semantic search and return results back to the user. The second major module in our system is the concept learning module. During the semantic search process, a MAS may discover that it needs to learn new concepts. The Concept Learning module helps that MAS to learn the new concepts from other MASs. A social network is used in communication between agents from different MASs.
In this research, we define two case studies to test the system. These case studies evaluate the efficiency of using social networks in representing relationships between agents in different MASs in learning new concepts from several teachers. We also introduce a novel approach of calculating tie strengths in social networks using Hidden Markov Model (HMM).
The results obtained show that using social networks in communicating between agents in different MASs has a positive effect in our system. During leaning new concepts, using social networks between the learner and the teachers gives betters accuracies in all concepts learnt and with different machine learning techniques used. On the other hand, using social networks decrease the negative effect of increasing number of teachers in the concept learning process.

abstract:
The last few decades of technological advancements provide many physical and virtual techniques of displaying information. Inspired by Joseph Bogen's idea of the Giant Walkthrough Brain, this thesis discusses the creation of three innovative methods that allow us to visualize and explore human brain anatomy.
First is the Giant Walkthrough Brain Show: a live virtual tour of a 3D brain museum in collaboration with science speaker Jay Ingram and his band that educates and entertains the audience using stories and music.
The second method is a standalone application that recreates elements from the show to provide a similar experience to individuals on their personal computers.
 Lastly, the Brain Slice Explorer is a blend of physical and virtual worlds: a sliced replica of a human brain can be taken apart and studied, while corresponding QR codes provide access to a web application with further information and details.

abstract: The theory of parametric harmonic generation is described in this thesis. It is shown that for Nth-order harmonic generation the time-varying parameter (P), such as elastance (S), capacitance (C), conductance (G), or resistance (R), exhibits N−1 periods of a sine wave under one sinusoidal pumping cycle, which is named sinusoidal representation of pumped parameters. The maximum conversion efficiency of reactive frequency multipliers is 1/N. The related P-V curves are described by the Chebyshev polynomials. Impulse representation of pumped parameters is also developed to represent a transient train of pulses to describe the resistive multipliers. Several circuits are designed to demonstrate the validity of the theory and explore the parametric circuits in millimeter-wave and sub-THz bands. A frequency tripler is designed in the 28-GHz 5G band, using the topology of symmetric antiparallel pair of series varactors to achieve about 24-dB conversion loss (CL), −8-dBm maximum output power (POUT), and 18% relative bandwidth (BW). Two reconfigurable frequency multipliers (RFMs) are designed based on antiparallel nMOS-varactor pairs (APNVP) and switched-capacitor varactor (SCV) pairs. The SCV can obtain the ratio of maximum-to-minimum capacitance as high as 20, almost 10 times better than that of MOS varactors. The SCV-based RFM demonstrates much better performance than the APNVP-based RFM. A resistive tripler based on an antiparallel diode-connected nMOS transistor pair is also designed and measured in the D-band, with wide 28% BW and −16 dBm POUT. The CL can be improved by increasing the non-linearity of the resistance by tuning the back-gate control voltage. A voltage-controlled inductor is proposed based on a transistor-controlled capacitor and demonstrated in a D-band injection-locked oscillator with a ≥16% tunable operating frequency range, dc power as low as 5.6 mW, and a compact 0.018-square-mm core size.

abstract: Ensuring household food security is an ongoing global concern. In Sri Lanka, years of civil war and natural disasters have posed a challenge in terms of decreasing poverty. One of the pathways out of poverty and improved food security is through smallholder aquaculture. With underutilized aquatic resources, the country is well placed to further develop aquaculture in the country including shrimp farming. Prior to expanding shrimp farming in the country, more information was needed about the current state of shrimp farming and the potential of this livelihood to provide an equitable pathway to food security. A cross-sectional survey of smallholder shrimp farmers (n = 225) was used to examine the socio-demographics, household food security, gender roles, sustainability of practices, and social networks of information exchange within the industry. Two provinces, the North Western Province (NWP) and Eastern Province (EP), were targeted as having established shrimp farms and the opportunity for expansion in the EP. Results demonstrated that the industry was male dominated and that farmers represented different demographics than the general Sri Lankan population. Women in the NWP participated in more on-farm activities compared to women in the EP. The majority of shrimp farmers were food secure and had a higher socioeconomic status than the general population. Men and women within the same household also perceived food insecurity differently. Farmers primarily utilized other farmers for information on shrimp production. Although the relationship is complex, the number of contacts a farmer had was associated with sustainable practices. A qualitative study of female shrimp farm owners revealed that few women own shrimp farms and a few of these women have experienced discrimination as women in the industry. Results indicate that a one-size-fits all intervention would not be appropriate in Sri Lanka as there are differences in farmers in the NWP and the EP, and certain groups of people may be more interested in shrimp farming. Courses and extension services should be available in both Sinhala and Tamil. Increasing women’s participation in shrimp farming should only be considered in light of cultural gender roles and motivations of women to work in shrimp farming.
