    Abstract:
    While there is support for various individual and contextual predictors of counterproductive workplace behaviour (CWB), little research has examined social rank and CWB. In this research, I examined social rank in terms of social dominance orientation (SDO), and leader dominance and prestige. Using data from a police organization (281 employees and 130 supervisors), I examined the association between employee SDO (time 1) and employee self- and supervisor-rated CWB (time 2). I also examined the association between perceived leader dominance and prestige (time 1), and employee self- and supervisor-rated CWB (time 2). Findings indicated that SDO was associated with CWB, and that both servant leadership and perceived social impact moderated this relationship. Findings also indicated that perceived leader dominance and prestige were associated with CWB, via leader trust. Findings contribute to the understanding of CWB as potential outcomes of social rank, highlighting the importance of moderating and mediating variables.

  • Investigating changes in Mangrove cover and conservation policy in the protected area of Yum Balam, Mexico, 1981-2020

    Resource Type:
    Thesis
    Creator:
    Maldonado Navarro, Denisse
    Abstract:
    Mangroves are highly important, endangered species that provide many environmental services. This research examines changes in the spatial extent of mangrove forest cover in the protected area of Yum Balam, in Mexico using data for the years 1981, 2005, 2015 and 2020, obtained from government agencies, together with a review of the history of mangrove conservation and the recent land management plan for the area. Results show an early period of losses, followed by a period of relative stability, culminating in a mix of losses in areas close to the urban centres of Chiquila and Holbox. A comparative analysis using spatial data obtained from Global Mangrove Watch and through Google Engine revealed inconsistencies, but similarities in the overall trend. Overall, the management plan favours tourism, allowing economic development in some sub-zones. Monitoring mangrove cover is important to identify drivers of change, and to elaborate informed policies for mangrove conservation.

  • Stress and Damage Analyses of Thermal Barrier Coatings Under Cyclic Thermal Loading Conditions

    Resource Type:
    Thesis
    Creator:
    Yan, Jinrong
    Abstract:
    The premature failure of the thermal barrier coatings (TBCs) system is a preliminary phenomenon that can significantly limit their applications in gas turbine engines. The delamination of TBCs occurs typically at interfaces between the top coat and bond coat due to thermal mismatch stress via both crack nucleation and propagation and decohesion. In this thesis, this phenomenon was studied using a multi-physics approach...exceeding text limit

  • Learning Recommender Systems with Deep Structured Low Rank Matrix Approximation

    Resource Type:
    Thesis
    Creator:
    Niknafs Kermani, Mahan
    Abstract:
    In this study we propose a Deep structured LOw Rank Matrix Approximation model (DLORMA) that incorporates additional stacked denoising autoencoders and local matrix approximations in a loosely coupled fashion. To the best of our knowledge, DLORMA is the first hybrid recommendation system that combines deep learning and low rank matrix approximation. Comprehend experiments based on three real datasets show improvements in prediction performance over other state-of-the-art recommendation systems.

  • Canadian Impact Assessment: Gender-Based Analysis Plus and Intersectionality in Natural Resource Policy

    Resource Type:
    Thesis
    Creator:
    Siddon, Stephanie Raye
    Abstract:
    This study seeks to examine how the federal government of Canada is applying Gender-Based Analysis Plus to Impact Assessment of natural resource projects, and to consider whether this constitutes an adequate application of intersectional policy analysis. Through a review of secondary literature and open-ended semi-structured interviews with key informants, this project examines the use of GBA+ in federal impact assessment, ultimately concluding that although improvements have occurred, much more work remains to be done to better align GBA+ with intersectional theory and practice.

  • Small Light Weight LiDAR Systems with Remotely Piloted Aircraft for Powerline Detection

    Resource Type:
    Thesis
    Creator:
    Moses, Samuel Junior
    Abstract:
    This thesis examines small low-cost light weight LiDAR systems for remotely piloted aircraft (RPA) for power transmission line (PTL) detection. Different PTL samples were used to understand how the low-cost light-weight LiDAR systems perform against them. A performance evaluation was done which included a specification comparison, data comparison, root-mean squared deviation comparison (RMSD) for both de-energized and energized PTLs and a sectional analysis. For the data comparison, the results showed LiDAR A performed better but not within the advertised precision for 5/6 of the test. The RMSD test resulted in the understanding in the accuracy of the data collected, lower deviations were found in the data collected by LiDAR B, but more consistent deviations were found in LiDAR A data. A conclusion was made that low-cost light-weight LiDAR systems would not be effective as a stand-alone system for PTL detection so it should be paired with an additional sensor.

  • The Knife's Edge of Visibility: Cruising, Surveillance, and Discursive Practices of Queer Communities in Ottawa

    Resource Type:
    Thesis
    Creator:
    Kenyon, Miles Jeffrey
    Abstract:
    This thesis investigates how men who have sex with men (MSM) discern, discuss, and defy issues of surveillance in the context of casual, public sex—also known as cruising—and how these exchanges constitute and inform subaltern countersurveillance measures. Focusing on written exchanges by users of the queer hook-up website Squirt, I analyze how users discuss safety and surveillance of cruising locations in the Greater Ottawa Area. This work concludes that surveillance and cruising is normalized, both police and ordinary citizens present safety risks, great care is taken to act discreetly and not infringe on the safety of non-cruisers, and environmental factors contribute greatly to the construction and circumvention of surveillance infrastructure. The data additionally complicate well-established perspectives on surveillance, including surveillance realism and introduce opportunities for queering and expanding future research.

  • Resonantly Forced Waves and the Effect of Tank Geometry on the Free Surface

    Resource Type:
    Thesis
    Creator:
    Cheng, Benjamin Aaron
    Abstract:
    This thesis examines the evolution of small-amplitude, resonantly forced fluid waves in a tank of finite extent. A rectangular and annular tank are considered, with the fluid in each tank subject to periodic lengthwise or radial forcing. The resonant forcing of fluid in a rectangular tank has been examined previously. How varying the geometry of the tank affects the evolution of the free surface is not yet fully understood. This work aims to contribute toward better understanding the interplay between geometric and resonant effects in axisymmetric geometries. Analytic and numerical results are used to examine the effects brought forth by varying the tank geometry. The responses in the rectangular and annular tanks can be qualitatively distinct. The inner radius of the annular tank is connected to the degree to which the underlying spectrum is commensurate, and this is shown to play a key role in determining how the results vary.

  • Regional Blood Flow Alterations Following Pediatric Concussion: A PedCARE+MRI Substudy

    Resource Type:
    Thesis
    Creator:
    Kardish, Rachel Valentine
    Abstract:
    This study examined whether cerebral blood flow (CBF) differed between children with concussion and orthopedic injury (OI) controls at 72 hours and 4 weeks post-injury. It also examined whether acute CBF and psychological resilience improved prediction of concussion symptoms beyond the existing 5P score prediction tool. 70 children with concussion (Mean age=13.05±2.02, 47% female) and 29 with OI (Mean age=12.59±1.97, 41% female) were included in this study. Regional CBF alterations were present in children with concussion versus OI, with some regional CBF varying over time. Specifically, increased CBF was found in anterior regions, and decreased CBF was found in posterior/temporal regions. Regional CBF, psychological resilience, and the 5P score combined did not predict 2- or 4-week concussion symptoms. Though clinical significance remains unclear, these results are important for understanding persistent neurobiological deficits after pediatric concussion, as they indicate clear regional CBF alterations.
