A parametric study of a tidal turbine hub retrofit’s influence on power generation and thrust
(University of New Brunswick, 2025-02) Corbett, Finley; Jeans, Tiger; Gerber, Andrew
For efficient tidal energy extraction using traditional horizontal axis turbines, it is desirable to maximize electrical power output and minimize thrust loads. This research addresses both factors by establishing a workflow to parametrically investigate the influence a co-rotating hub retrofit has on the hydrodynamics of an existing horizontal axis tidal turbine using Computations Fluid Dynamics (CFD). Within the parametric space of the 21 high-fidelity simulations performed, it was concluded that the net effect of the retrofit did not improve power generation, but reduced thrust by a maximum of 0.21%. While isolated torque imparted on the primary blades increased, an added counter-acting moment directly caused by the retrofit neutralized this effect. Primary blade load influence after the retrofit was added was caused by the retrofit tip vortex, the modification of the primary blade relative flow angles, and the increase in horseshoe vortex strength at the root to hub junction.
Borderline personality vulnerabilities for intimate partner violence perpetration in a non-forensic sample: Developing a typology and theoretical model
(University of New Brunswick, 2025-02) Doyle, Jessie Nicole; Campbell, Mary Ann
Research demonstrates that intimate partner violence (IPV) perpetrators are heterogeneous (Corvo & Johnson, 2013). Borderline personality disorder, a mental health condition reflecting a pervasive pattern of interpersonal and identity dysfunction, emotion dysregulation, and impulsivity (APA, 2013), has often been recognized among IPV perpetrators (Spencer et al., 2019). Nonetheless, not all IPV perpetrators have BPD traits, nor do all people with BPD traits perpetrate IPV. Better understanding a ‘borderline subtype’ of IPV perpetrators may help discern which BPD features are predictive of IPV behaviours (physical, psychological, sexual). The current research utilized online recruitment strategies to: (1) identify latent profiles of self-report BPD features, insecure attachment, and anxiety sensitivity (AS) among a non-forensic sample; (2) distinguish latent profiles on their reported IPV behaviours; (3) test the explanatory value of attachment dimensions and AS in the BPD-IPV pathway; and (4) investigate the validity of BPD features over and above traditional criminogenic risk factors in predicting IPV behaviours. From the final sample of community-based members (N = 451, Mage = 31.98, 62.7% men), two profiles emerged via latent profile analysis: (1) insecure attachment-specific (IAS, n = 90) and (2) mixed borderline features (MBF, n = 361). MANOVAs revealed that the MBF profile endorsed significantly more frequent and severe IPV behaviours and criminogenic risk factors. Structural equation modelling demonstrated that insecure attachment and AS partially mediated relations between BPD and IPV. Hierarchical regression analyses and canonical correlation analyses indicated that BPD features and traditional criminogenic risk factors each have incremental validity in predicting IPV behaviours. Correctional implications include adding BPD features to existing IPV risk assessment tools. Clinically, results corroborate the notion that addressing heterogeneity in IPV offenders is important for tailoring evidence-based interventions to the unique needs of offenders (Butters et al., 2021). Whereas insecure attachment-specific offenders might benefit from attachment-based or emotionally-focused couples therapy, mixed borderline features offenders would likely require interventions that focus on enhancing emotion regulation (e.g., dialectical behaviour therapy). Overall, the present findings support the need to tailor IPV interventions, and continue investigating the role of BPD features in IPV behaviours to maximize the utility of current risk assessment tools.
Pre-Service Teachers of French as a Second Language and the Construction of a Professional Identity
(American Educational Research Association, 2022-04-24) Le Bouthillier, Josée; Culligan, Karla; Kristmanson, Paula
This study explores the development of linguistic competence and confidence of pre-service French as a second language (FSL) teachers enrolled in a teacher education program in New Brunswick, Canada. In addition to their regular program requirements, participants in the study engaged in a series of language support sessions. We collected French oral proficiency assessment results pre- and post-sessions and focus group interview data. The analysis shows that participants' language proficiency increased over the course of the sessions and the program. Interview data reveal professional identity-related themes such as confidence, and the importance of safe spaces for interaction and mediation. Implications for FSL teacher recruitment and retention are given, specifically with regard to teacher candidates' need for certain types of support.

Feasibility of producing non-structural wood products using trembling aspen lumber
(University of New Brunswick, 2025-01) Zhang, Mengyuan; Gong, Meng; Chui, Ying-Hei
Trembling aspen (Populus tremuloides) is abundant in Canada but underutilized in non-structural solid wood products. This study was aimed at evaluating the feasibility of using aspen lumber to produce flooring, moulding, and siding. The shrinkage, surface roughness, and wettability of aspen wood were tested. The surface hardness, screw withdrawal resistance, colour change, and dimensional stability of three products fabricated were examined. The wood yield of each product was analyzed. It was found that aspen showed superior machinability and wettability to silver maple and yellow poplar. Aspen flooring had a Brinell hardness of 13.47 MPa, 60% lower than silver maple. Aspen moulding exhibited a screw withdrawal resistance of 23.42 MPa, 15% higher than eastern white pine. Aspen siding showed comparable colour and dimensional stability to spruce-pine-fir wood. The aspen wood yields were estimated to be 38.25%, 25.4%, and 49.2% for flooring, moulding, and siding, suggesting its potential for non-structural applications.
