Item Different scenarios of electric vehicle contribution to power system voltage instability(2025-12)Electric vehicles (EV) are a relatively large load with completely different load characteristics from other conventional power system loads. Many studies have already been carried out on issues like increased peak demand, voltage reduction, harmonics, and over-loading the distribution systems. However, scant attention has been paid to the impact of EV on the power system voltage stability. Load power restoration following a sudden change in the system voltage is one of the most important factors contributing to a possible voltage instability. Induction motors, load behind on-load tap changer (OLTC), and the thermostatic loads are the three well-known short-term (seconds), medium-term (minutes), and long-term (tens of minutes) load power restoration mechanisms, respectively. This paper aims to show how the local load bus measured voltage, and current can be used to predict on-line a voltage collapse caused by the EV in conjunction with other types of load power restoration dynamics. A combination of conventional loads and the EV load with a new voltage-power relationship are considered and different scenarios are clearly presented. The proposed method is confirmed using MATLAB simulations. The findings of this study may help to anticipate and avoid a possible power system blackout by assessing online the power distance from the stability limit.Item Glitched bodies: Aberrant distortions, machine vision, and spatial dislocation(2025-11)This poster explores aberrant distortions, glitches, and spatial representation beyond the body, drawing on the theoretical frameworks of Hito Steyerl, Rosa Menkman, and Owen Hopkins. Steyerl’s concept of the "poor image" and degraded visuality, alongside Menkman’s aesthetics of the glitch, reveal how machine-mediated perception reshapes spatial and bodily representation. Hopkins’ insights into architectural representation inform how digital and forensic imaging alter spatial fields, destabilizing fixed perspectives. Through the lens of illustration through the machine vision is examined as a reconstructive and interpretative tool, producing fragmented, non-human perspectives that challenge traditional notions of spatial legibility. The intersection of these concepts highlights how errors, artifacts, and breakdowns in image-making processes expose underlying biases in technological perception. By illustrating the dislocation of the body within machine-generated perceptual fields, this work interrogates the limits of human-centric representation and explores how technological distortions mediate our spatial and forensic realities.Item Addressing intimate partner stalking in Pacific contexts: A critical review of the literature(2025-12)This presentation reports on a critical review of literature examining social work approaches to intimate partner stalking within Pacific families in Aotearoa, identifying key themes as well as gaps in both the evidence presented and the interventions utilised. Intimate partner stalking is a serious form of coercive control and a major predictor of escalating harm or homicide in family violence cases. In mainstream family violence research, stalking behaviours are well-documented and associated with high risk. However, a comprehensive review of available literature reveals that stalking is rarely examined as a distinct behaviour within Pacific family contexts. Actions such as persistent calling, constant messaging, following a partner, or showing up unannounced are often normalised as showing ‘care,’ ‘jealousy,’ or ‘family duty.’ Social workers who engage with Pacific families often rely on generic family violence risk assessment tools that do not capture these cultural nuances. As a result, stalking behaviours can be misread or underestimated and thus underreported and unaddressed. The presentation highlights the paucity of culturally responsive approaches to identifying and challenging stalking behaviours. The gaps in both knowledge and practice uncovered pose significant risks to victim safety and can lead to culturally inappropriate interventions. The literature review is the first stage of a larger project aiming to develop a culturally responsive social work model for addressing this critical issue for family violence prevention, one that integrates Pacific cultural values and effective forms of community engagement and support.Item Hidden in Plain Sight: The Social Impact of the Narrative (encoded meanings and creative interventions)(2025)The social research project Hidden in Plain Sight centres its examination on trauma-related mental health, and body autonomy issues connected to individuals who identify as female within New Zealand society. Charlotte Perkins Gilman’s nineteenth century short story, “The Yellow Wallpaper” functions as the project’s conceptual framework and the anchorpoint between social-histories, intellectualism, and the political landscape. This socio-political composition is also positioned as a cultural marker with narrative functioning as a mechanism for memory recall. Wallpaper operates within the context of this project as a sophisticated skin embedded with meaning, linked to language as a plurality of signs. It is also viewed as an overarching signifier of patriarchal oppression, by taking the private “public” ornamental decoration becomes a metamorphic emblem of contemporary activism. Hidden in Plain Sight is a practice-led inquiry which employs research-creation as a methodology specifically, in association to the artist-pedagogy. Research-creation in this context is viewed as a multidimensional framing that investigates engagement as a radical form of enrichment. The international art collective Fluxus has been instrumental in unpacking the social-hybrid within contemporary practice including the digital territories as an extension of the relational network. Fluxus’s events have been redefined for the purpose of this research as performance installation-sites. French philosopher Jaques Rancière’s frameworks of intellectual emancipation and dissensus have also been engaged, wherein art is positioned as a specific sphere of experience that is reconfigured as a rupture to histories by redrawing boundaries.Item Do sustainability committees make a difference?: Carbon reduction efforts in New Zealand-listed companies(2025-12-01)PURPOSE This study investigates the role of the sustainability committee as a governance mechanism in reducing carbon emissions and carbon intensity among New Zealand's listed companies. METHOD Using a longitudinal panel dataset covering the NZX Top 50 firms from 2021 to 2024, the research applies fixed-effect regression models to test the relationship between governance structures and two dependent variables: carbon emissions and carbon intensity. FINDINGS The authors confirm prior findings of a negative relationship between the presence of a sustainability committee and the firm's carbon emission and intensity. These findings indicate the active role that the sustainability committee plays in reducing carbon emissions. ORIGINALITY / VALUE The research is novel because it examines an emerging governance mechanism (sustainability committees) in a newly regulated and under researched market. This study utilises two complementary carbon performance indicators, emissions and intensity. It provides practical guidance for boards and regulators while contributing to the international evidence base on how participants with governance structures shape climate-centric outcomes.
