(ACM, 2025) Konig, Jemma; Bidois, Ben; Manchester, Ryan; Head, Mitchell; Owen, Mahonri; Hoskens, Merel; Dwivedi, Anany; August, Luke; Fredericks, Joel; Yoo, Soojeong; Tran, Tram Thi Minh; Pantidi, Nadia; Hoang, Thuong; Hoggenmueller, Marius; Caldwell, Glenda; Tag, Benjamin; Andres, Josh; Davis, Hilary; Boden, Marie; Zhu, Howe; Harman, Joel; Rahman, Jessica
The use of wearable devices in HCI research is becoming more common. However, it is also widely accepted that there are challenges associated with the use of wearable devices. Researchers have investigated generalized challenges, and more recently, challenges associated with low-cost commercial devices. Yet, little work has been published on the challenges of working with higher-cost research-grade devices. In this paper, we use a case study to explore the challenges associated with research-grade devices, and compare these challenges with those that have been identified by other researchers. The case study involves the use of two research-grade devices to record a series of physiological data-points. The case study identified one new challenge that is associated with research-grade wearable devices (setup complexity (researcher adoption)) and highlighted similarities between generalized challenges, low-cost device challenges, and research-grade challenges. The findings from this work can be used to further investigate challenges associated with wearable devices.
Academic misconduct among undergraduates across Aotearoa: Insights and implications for policy and practice
(Springer, 2024-03-26) Stephens, Jason M.; Absolum, Kate; Adam, Lee A.; Blickem, Chelsea J.; Gilliver-Brown, Katherine E.; Hart, Deirdre E.; Kelly, John; Olsen, Wendy; Ulrich, Neil
As elsewhere in the world, academic misconduct is a serious problem in Aotearoa. Yet, beyond the occasional newspaper headline, we know relatively little about the extent of the problem here or the factors associated with it. Consequently, our educational leaders and practitioners are left under-informed as they seek to address the problem and promote academic integrity. To help provide the knowledge and insights needed to craft good policy and best practice, the Research on Academic Integrity in New Zealand (RAINZ) Project—a research collaboration involving eight tertiary institutions—was founded in 2021. In the second semester of 2022, the RAINZ Project launched the first-ever nationwide survey of undergraduate students’ perceptions, attitudes, and behaviours related to academic integrity. Results from this survey, which was completed by undergraduates (N = 4493), indicate that most students (approximately two-thirds) reported engaging in at least one form of academic misconduct in the past year. As hypothesised, students’ perceptions (of the institutional climate and peer norms) and moral attitudes (related to cheating) were significantly associated with their engagement in academic misconduct. Details of these results as well as their implications for policy and practice are discussed.
A multi-objective decision-support framework for early-stage cost–carbon–process-hour screening of prefabricated cold-formed steel residential framing in New Zealand
(The University of Waikato, 2026) Ramani, Kevin; Lim, James Boon Piang
Early-stage configuration decisions in prefabricated cold-formed steel (CFS) residential framing can influence process cost, A1–A5 embodied carbon, and construction process-hours before detailed structural verification, procurement, and construction planning are complete. In the New Zealand residential construction context, these decisions are important because panel rationalisation, truss rationalisation, opening/detailing complexity, and prefabrication level affect how work is distributed across factory production, transport, logistics, and site installation. As a result, single-objective assessment is insufficient for comparing alternative framing configurations. This thesis develops a multi-objective decision-support framework for early-stage cost–carbon–process-hour screening of prefabricated CFS residential framing in New Zealand. A project-derived residential framing package is represented using the decision vector 𝐱=[𝑅𝑝,𝑅𝑡,𝑂𝐶,𝑃𝑓], where 𝑅𝑝 and 𝑅𝑡 represent panel and truss rationalisation intensity, 𝑂𝐶 represents opening/detailing complexity, and 𝑃𝑓 represents prefabrication level. Three objectives are minimised simultaneously: CFS framing process cost, A1–A5 embodied carbon, and CFS framing process-hours. A model-calculated S2 reference configuration is used for normalisation, comparison, and robustness assessment. An LHS-initialised NSGA-II optimisation procedure was used to generate nondominated cost–carbon–process-hour alternatives within the fixed case-study boundary. The reported optimisation run produced 8,302 feasible nondominated configurations without hard constraint violations, of which 2,695 achieved simultaneous reductions in predicted process cost, embodied carbon, and process-hours relative to S2. The remaining nondominated configurations are interpreted as trade-off alternatives rather than universal improvements over the reference case. Model credibility was assessed through S2 reasonableness checking, coefficient-audit traceability, convergence diagnostics, sensitivity analysis, constraint testing, multi-seed stability checking, and Monte Carlo robustness assessment. The results indicate that improved performance is achieved through coordinated rationalisation, detailing simplification, and prefabrication control rather than by maximising any single variable independently. The contribution of this thesis is an applied-methodological decision-support workflow for screening prefabricated CFS residential framing configurations before detailed structural design, contractor pricing, life-cycle assessment, and construction scheduling.
Testing the correspondence between self-reported and actual culturally valued behaviours in Māori students across Māori and non-Māori environments
(The University of Waikato, 2026) Shadrock, Mariah-Paige; Fox, Ririwai
Applied Behaviour Analysis (ABA) views culture as a network of interrelated behaviours maintained by social reinforcement within a shared verbal community (Baer et al., 2005; Bishop et al., 2009; Skinner, 1957). Within this framework, culturally valued behaviours (CVBs) for Māori—such as helping and contributing to the collective—are shaped and sustained through social consequences that reflect shared cultural practices (Baum, 2005; Bishop et al., 2009; Skinner, 1957). Despite their importance, these behaviours are rarely observed directly; researchers often rely on self-report measures, which represent a form of verbal behaviour available only to the speaker (Nisbett & Wilson, 1977; Skinner, 1957). Studies indicate that self-reported behaviours and observable actions often correlate only modestly (Baumeister et al., 2007; Dang et al., 2020), suggesting that verbal endorsements of values or intentions may not reliably predict actual behaviour. The Māori Cultural Embeddedness Scale (MaCES; Durie, 2001; Fox et al., 2023; Mead, 2003) was developed to assess engagement with Māori cultural values and practices. However, it remains unclear whether Māori individuals’ self-reported behaviours, as measured by the MaCES, reflect their actual behaviour (Durie, 2001; Fox et al., 2023; Mead, 2003). From an ABA perspective, correspondence between reported and observed behaviours must be demonstrated empirically rather than assumed (Cooper et al., 2020; Michael, 1982; Skinner, 1953). Guided by both ABA and Kaupapa Māori principles (Bishop, 1996; Bishop & Berryman, 2006, 2009; Smith, 1999), the present study addressed this gap by examining the alignment between Māori students’ self-reported and directly observed helping behaviour in Māori and non-Māori environments. Self-reported CVB was assessed using the Culturally Valued Behaviour Scale (CVB), a Māori cultural values and practices survey. One item (Q12) was drawn from the MaCES and was explicitly related to helping and used to analyse culturally valued helping behaviour (Durie, 2001; Fox et al., 2023). Twenty-three Māori students participated and were randomly assigned to either Te Kohinga Mārama Marae or a standard university psychology laboratory. Participants set up the room, completed the CVB (during which the observer intentionally dropped papers), and then packed up, while helping behaviours were recorded. Spearman’s rho assessed the correspondence between self-reported and observed helping within each context (Field, 2018). An independent t-test examined differences by environment and sex, while ANOVA assessed differences across age groups (Cohen, 1992). Results showed no significant correspondence between self-reported helping (Q12) and observed helping in either setting. Helping frequency remained consistently high across both environments, with no significant differences by environment, sex, or age. The CVB demonstrated acceptable internal consistency (α = .743), although item-level analyses suggested that behaviours clustered rather than showing uniform endorsement (Fox et al., 2023). Qualitative responses indicated that participants’ helping was motivated by intrinsic prosocial values rather than direct demands or perceived obligation (Baum, 2005; Biglan & Glenn, 2013). Overall, the findings suggest limited “say-do” correspondence for culturally valued behaviour in this sample (Baer et al., 1968; Nisbett & Wilson, 1977). Verbal endorsements of helping appeared to be governed by different contingencies than overt behaviour. Contrary to expectations, the Māori environment did not increase helping frequency or strengthen correspondence relative to the non-Māori setting. These results contribute to Māori-centred behavioural research by highlighting the complexity of measuring culturally valued behaviours and emphasizing the value of multimethod approaches that combine Kaupapa Māori perspectives with direct behavioural observation (Bishop et al., 2009; Smith, 1999). Future research should explore additional culturally grounded behaviours, expand opportunities for helping, examine how environmental contingencies within Māori settings may more strongly evoke or differentiate culturally valued actions, and investigate the difference between manded versus naturalistic behaviours to better understand how culturally valued actions are expressed across contexts (Cooper et al., 2020; Michael, 1993).
