Fitting Puzzles into Traditional Teacher-Centered Mathematics Classrooms: An initiative to bringing Logical thinking into classroom learning
(2024-07-12) Bajaj, Sunil; Kaur, Jasneet
Mathematical games, puzzles and stories involving numbers are useful to enable children to make connections between the logical functioning of their everyday lives to that of mathematical thinking and to build upon their everyday understandings (NCERT,2006). Mathematical puzzles can engage students in rich mathematical explorations and logical reasoning in the classroom (Evered, 2001).This poster aims to showcase the extensions and variations of the famous Japanese puzzle known as 'KenKen.' Inspired by this puzzle, a new set of puzzles called 'Harbans Puzzles' has been developed. The poster will provide a visual representation of these puzzles and their unique features. Furthermore, it will highlight the responses and experiences of students who participated in an outreach program called 'Har ghar Har Gali bujho Paheli,' organized by SCERT, Haryana, for government school students at all levels. Through this poster, we claim that the power of this kind of puzzles showcase the students' engagement and enthusiasm in tackling these mind-bending challenges as well as provide the alternate to boring exercises and practice of Mathematical procedures in an open and fun loving ways
Micro Versus Mega: Differences In Influencer Content
(2022-12-12) Mulholland, Stacey; Lang, Bodo; Lee, Michael; Bentham, Catherine; Harrigan, Paul; Brush, Greg
This paper explores differences in sponsored content across social media influencers. Using theories of influencer marketing developed by previous literature, this exploratory study uses through content analysis to investigate the relationship between influencer follower size (micro-influencer or mega-influencer) and the types of sponsored content they produce, as well as their disclosure of sponsorship. Fifty-four influencers and sponsored videos from YouTube were collected and analysed. Consumer perceptions of micro-influencers as more authentic and less commercial were reflected in the types of content they produced. Overall, micro-influencers had a lower rate of sponsored videos, and disclosed in less obvious and less commercial ways. This paper provides two key contributions by developing a better understanding of influencer typologies and providing empirical support of a trade-off between mega-influencers' reach and power, and micro-influencers perceived authenticity and intimacy. Importantly, the paper also highlights the need for greater education around disclosure for micro-influencers.
Evaluating Seismic Inertia Demand of Precast Concrete Diaphragms: A US-NZ Comparison
(2024-01-01) Yu, Tingting; del Rey Castillo, Enrique
Precast concrete diaphragms play a critical role on the seismic performance of structures, and increasing attention is being paid to strengthen these structural elements in the aftermath of the 2010/2011 Canterbury earthquakes. However, a significant gap remains in our understanding of the seismic forces that diaphragm elements should be assessed or designed for. Various key parameters affecting the seismic demands of diaphragms such as higher mode effects, plan and vertical irregularities and the role of over-strength capacity of the lateral resisting elements are not comprehensively addressed in current design and assessment documents. These missing aspects have raised questions about the adequacy of the simplistic design methods commonly used in national documents. The New Zealand loading standard NZS 1170.5 specifies a pseudo-Equivalent Static Analysis (pESA) approach for calculating diaphragm forces, taking into account Peak Ground Acceleration (PGA) and structural overstrength. Conversely, the US loading standard ASCE 7-22 introduces an alternative method for precast concrete diaphragms, utilizing a diaphragm design force reduction factor, Rs, while also including considerations for higher mode effects and structural overstrength. These aspects often lead to higher force demands compared to the general method in ASCE 7-22, used for other diaphragm types, but the accuracy of these methods in estimating diaphragm demands remains an open question. This study aims to bridge this gap by conducting a comparative analysis of the NZS1170.5 and US approaches to determine seismic forces demand in the diaphragm. The various documents are brought to a comparable framework by aligning key seismic design parameters such as response spectra, ductility and overstrength. The diaphragm forces were calculated using both standards and on a representative New Zealand building archetype to assess the efficacy of each standard's approach. The findings of the study offer critical insights into the calculation of diaphragm forces under US and NZ standards. This research contributes significantly to the field by aiding engineers in making informed decisions regarding the seismic design and assessment of buildings, ultimately enhancing structural resilience in earthquake-prone areas.
Predator Free 2050: Social and Ethical Challenges
(2024-07-29) Palmer, Alexandra
Projects aiming to suppress or eradicate introduced species often encounter social conflicts, which may be products of competing value systems [30, 31, 47]. Social, cultural, and ethical values are therefore increasingly recognised as necessary considerations in introduced species management projects [81, 14]. Where they have not been adequately considered, conflict has followed and projects delayed (e.g. Lord Howe Island) [163, 68]. Predator Free 2050 (PF2050) – Aotearoa New Zealand’s (NZ’s) bid to eradicate rats, possums, and mustelids by 2050 – will be vulnerable to such conflicts. New Zealanders hold a diverse array of attitudes towards animals, nature, predator control tools, and the state, not all of which necessarily align with PF2050 [14, 142, 163]. Yet because PF2050 is a nationwide campaign requiring active support from communities across the country, it requires an especially high level of support over a long period [14]. An initial step towards mapping social and ethical challenges was taken by the BioHeritage Challenge Bioethics Panel of academic, industry, and community experts [14]. This was an important horizon-scanning exercise, but more empirical research is needed to understand what New Zealanders might object to or disagree about in relation to PF2050, why, and whether any pro-active resolutions are possible. The goal of this research was to begin to provide some of this information using qualitative research and a choice modelling survey.
Double-cab utes: causes and consequences
(2021-05-12) Woodward, Alistair; Wisniewski, Mia; Wild, Kirsty
The double-cab ute is extraordinarily popular – the top five best-selling new vehicles in New Zealand (NZ) in 2019 were in this category. This is new: until 2015 the top-sellers were much lighter vehicles like the Corolla, and the trend is global. In the US light trucks (utes and SUVs) make up 70% of new automobiles, and they weigh more than ever: between 2000 and 2019 the average US pickup put on 520 kg. Designed for commercial activities such as construction and farming, these vehicles are now commonly used for short urban trips previously undertaken by light cars. There are consequences. The predominance of diesel engines means higher emissions of NOx and other local pollutants. Weighing 2 tonnes or more, fuel efficiency is reduced, and greenhouse emissions per km increased, relative to lighter vehicles. The height and width of these vehicles dominate road space. There are safety issues, including blind spots, a high centre of gravity, and an unforgiving front end. We estimate the effects of the recent rise of the ute in NZ on greenhouse emissions and road crash injuries. We explore also the effects of more, bigger, heavier, and more powerful vehicles on the quality and safety of public spaces and the experience of those who use these spaces. We will summarise work done on the promotion of the double cab ute in this country, contrasting the themes that run through advertising images and commercial messaging with driver surveys and studies of driver behaviour. The increasing average mass of the New Zealand vehicle fleet, embodied in the double cab ute but apparent in other vehicles also, challenges climate goals, urban efficiency, and health and safety plans such as Vision Zero. There is clearly a need for integrated solutions that will protect the health and sustainability of the New Zealand transport system.

(2025-02-24) Mika, Jason Paul; Niu, Xiaoliang; Ace Consulting
This report explores Māori engagement with China and its people, past, present, and future, both here in Aotearoa New Zealand (‘New Zealand’) and in the People’s Republic of China (‘China’). Its purpose is to support a balanced and resilient relationship between New Zealand and China, with a focus on Māori-Chinese relations at a prominent level, tracing their historical, cultural, and economic connections. The report assembles insights from written records and first-hand accounts of Māori, Chinese, and Pākehā people into Māori-China engagement. It covers four aspects: early Māori engagement with China, current business relations, other contemporary links, and future opportunities with recommendations.
Assessing a statistics capstone course against a university’s graduate profile attributes framework
(International Association for Statistical Education, July 2024) Passmore, Rachel; Pfannkuch, Maxine
Compulsory capstone courses were introduced in 2019 for all undergraduates in the Faculty of Science in recognition that students required support to transition from being a student of a discipline to a practitioner. These capstone courses required the University of Auckland graduate profile attributes to be assessed. This research aimed to discover how a generic institutional framework could be used and if it provided insights into the statistics discipline. Coursework submitted by two cohorts of students enrolled in the statistics capstone course were examined. This paper demonstrates that the use of a generic framework provided a new lens on statistics capstone course assessment and prompted an awareness of the skills and knowledge needed to improve the transition from university.
Towards posing and answering questions about bar graphs
(International Association for Statistical Education, July 2024) Puloka, Malia S; Pfannkuch, Maxine
Posing questions about categorical variables and answering them using representations is a neglected area of research. A small exploratory study was conducted with 13-14-year-old Pasifika and Māori students using culturally appropriate data and pedagogy. Data collection included pre and post-tests and a video-record of a 10-lesson implementation. The findings indicated novice students could learn to pose quantitative questions about categorical variables but struggled to deconstruct questions and to decode representations to answer simple, conditional, and joint questions. The implications of the findings are discussed.
Learning to advocate with data in a modelling environment
(International Association for Statistical Education (IASE), July 2024) Patel, Anne; Pfannkuch, Maxine; Kaplan, Jennifer; Lübke, Karsten
Modelling data can provide students with experiences to develop their understanding of contributing factors to a data-based situation, their ability to offer ideas towards solving a problem, and their written communication around decision-making, argumentation, and advocation for change, a nascent area of research. Motivated by personally relevant societal issues, novice 11-year-old students were introduced to a mechanistic modelling approach using TinkerPlots, with the aim of replicating underlying distributions to simulate phenomena seen in data. Follow Up Tasks to Model Eliciting Activities were used to support and enhance students’ statistical writing about their modelling process, and their argumentation, decisions, and recommendations. The findings indicate that students’ written communication and advocacy could be improved.
Supercapacitor-battery hybrid energy storage for portable smart devices using supercapacitor swapping energy harvester
(Institute of Electrical and Electronics Engineers (IEEE), 2024-11-06) Dissanayake, Kavishka; Kularatna-Abeywardana, Dulsha; Patel, Nitish; Kularatna, Nihal
A novel hybrid energy storage mechanism for portable smart devices that combine supercapacitors and batteries is proposed. Supercapacitors offer rapid charging and high-power delivery, which are ideal for short bursts of power activity, and batteries provide long-term energy storage. The system incorporates a solar energy harvester that efficiently charges the supercapacitor. A unique swapping converter topology allows for quick replacement of depleted supercapacitors with charged ones. This hybrid approach along with the solar harvester aims to extend device operation and reduce reliance on conventional battery charging methods and converters.
Moderate milling improved storage stability of quinoa based on the evaluation of lipid oxidation and physicochemical characteristics
(Wiley, 2025-02) Ni, Danfeng; Gao, Feng; Cao, Hongwei; Song, Hongdong; Huang, Kai; Zhang, Yu; Wang, Xiaoxue; Tan, Zhigang; Lu, Jun; Guan, Xiao; Grim, Nabil
This study investigated the storage stability of quinoa across various milling degrees (MD) concerning lipid oxidation and physicochemical characteristics during different storage durations. The process of milling induced tissue disruption, potentially facilitating contact between internal components and air, thereby impacting the storage stability of quinoa. The findings highlighted that cooking quality and textural properties exhibited a more pronounced improvement from MD 19% to MD 27% over a 6 M storage period. Notably, peak viscosity demonstrated a negative correlation with springiness and a positive correlation with water absorption of milled quinoa throughout storage. Thermal property analysis indicated that the increase of storage time and the decomposition of fatty acids triggered heat release, consequently reducing the enthalpy (ΔH) in milled quinoa. Scanning electron microscopy further exposed the oxidation of lipids in quinoa with varying MD during storage. In contrast to quinoa with higher degrees of milling, quinoa with MD 19% showcased superior textural characteristics and enhanced storage stability.
Foraminiferal evidence for the provenance and flow history of turbidity currents triggered by the 2016 Kaikōura Earthquake, New Zealand
(Taylor & Francis, 2024-07-02) Hayward, Bruce W; Sabaa, Ashwaq T; Howarth, Jamie D; Orpin, Alan R; Strachan, Lorna J
The 2016 Mw 7.8 Kaikōura Earthquake triggered simultaneous turbidity currents down ten submarine canyons along a 200 km stretch of the continental slope, east of New Zealand. Some discharged into the Hikurangi Channel which flows >1500 km northwards along the abyssal trench floor. To better understand provenance continuity in deep-sea sedimentary records, foraminiferal samples from the 2016 turbidites from 17 canyon and channel cores were used to investigate the source histories of these submarine gravity flows. Cluster analyses suggest the canyon provenances for most 2016 turbidite faunas should be determinable using a combination of the relative abundance of key benthic genera, planktic foraminiferal index (dissolution), absolute test abundance and planktic % of the foraminiferal faunas. Two ordinations (PCA, PCO) based on these parameters were used to infer provenance and flow history. One hundred kilometres down the Hikurangi Channel, faunas in the 2016 turbidite confirm a Kaikōura Canyon source. Further downstream, 200–500 km north of the confluence with Campbell, Cook and Opouawe canyons, faunas indicate that the 2016 turbidite in the northern Hikurangi Channel is a composite deposit, from an initial Opouawe-Cook canyon-sourced turbidity current over-ridden and partly mixed with, a Kaikōura Canyon-sourced flow that arrived sometime later.
Understanding sedimentary systems and processes of the Hikurangi subduction margin; from Trench to Back-Arc. Volume 2
(Taylor & Francis, 2024-07-02) Strachan, Lorna J; Orpin, Alan R; Bland, Kyle J; McArthur, Adam D; Bailleul, Julien
This is the second of a two-part New Zealand Journal of Geology and Geophysics Special Issue on understanding sedimentary systems in Aotearoa-New Zealand’s Hikurangi Subduction Margin (HSM). This volume includes six research papers that explore sediment-tectonic interactions operating over a range of spatio-temporal scales. We take a distinctive perspective moving from the subduction deformation front in the Hikurangi Trough, upslope to the subduction wedge, and onshore to the Coastal Ranges. Temporally, papers span the onset of subduction in the Miocene, to disentangling provenance of turbidity currents triggered by the 2016 CE Kaikōura Earthquake. Collectively, the studies in the special issue reveal a complicated and continually evolving margin, where active tectonics and volcanism, coupled with vigorous climatic and oceanographic drivers, modulate erosion, transport, and depositional cycles of vast volumes of terrigenous sediment into ocean basins. Despite decades of significant research advances in our knowledge of the HSM, considerable scope remains for future work. A deeper understanding of fundamental tectonic-sediment interactions operating on active margins, along with the significant geohazards they pose remain outstanding research needs. Collectively, Volumes 1 and 2 highlight enduring interest in the HSM as a globally important natural laboratory for the study of subduction zone geoscience.
Surgical Innovations in Dysphagia Management
(Springer Nature, 2025-12-01) Allen, Jacqui
Purpose of Review: Discuss current surgical advancements and options in the management of swallowing disorders and dysfunction. Recent Findings: A wide range of surgical procedures can be considered for management of deglutitive disorders and is determined by underlying pathology. Novel options include endoluminal access for cricopharyngeal myotomy (Z-POEM), stem cell application in tongue regeneration and improving salivary gland function, and bioengineering approaches to vocal fold regeneration to assist in airway protection. Additional novel surgical procedures are needed to address the complexities of swallowing disorders. Summary: Surgical airway protection, removal of obstruction to flow and enhancement of bolus dynamics offer different ways to improve swallowing. Practitioners are improving current techniques and exploring additional options including bioengineering approaches, endoluminal surgery and airway protection. There is still room for innovation in surgical swallow management as current options remain limited.
Community researchers in end-of-life care research addressing intersectional inequalities: A rapid realist review and evaluation of the why, the how, for whom and in what circumstances
(BMJ Group, 2025-02-14) Akhter Hussain, Jamilla; Fargin, Mariam; Booth, Andrew; Begum, Samina; Sher, Inayah; Bashir, Shabina; Clowes, Mark; Gott, Merryn
There is limited understanding about the end-of-life experiences of intersectionally marginalised groups. A potential way to support greater access and inclusion of such individuals in research is to have community researchers as part of the core research team. Community researchers here are defined as individuals with similar social identities, heritage and location to the research participants of interest. However, how best to work with community researchers in the context of structural inequalities at the end-of-life remains poorly understood.

Considerations for development of pregnancy and postpartum physical activity and exercise guidelines in New Zealand
(Sports Medicine New Zealand, 2023) Hume, Patria A; Wyatt, Hannah E; Barnett Collins, Juno; Waller, Nimisha; Crowther, Susan; Brown, Wendy J
Background: The SMNZ information pamphlet “Women in Sport Exercise and Pregnancy” was produced in 1994. In recent years several countries have produced comprehensive guidelines for physical activity during pregnancy, based on systematic literature reviews and expert consensus. There are however no guidelines for physical activity and exercise (PAE) during pregnancy for Aotearoa/New Zealand (NZ). In order to reflect the range of cultures in NZ, including those of Māori and Pacific peoples, it is important to develop NZ-specific guidelines. Objective: To determine factors for consideration in developing NZ guidelines for physical activity and exercise during pregnancy and postpartum (childbirth continuum). Methods: A review of international published guidelines on exercise during pregnancy was conducted. Findings from in-progress Te Kukunetanga (Developing Cycle of Life) studies were considered for the NZ context. Results: Initial findings from Te Kukunetanga pregnancy research indicated that physically active women experienced inconsistent and conflicting information about exercise during their childbearing years in NZ. PAE could be better facilitated if health care providers provided accurate tailored advice and information informed by trustworthy relevant evidence. Although narrative reviews were conducted by professional bodies such as American Congress of Obstetricians and Gynaecologists (ACOG) and Royal Australian NZ College of Obstetricians and Gynaecologists (RANZCOG), no guidelines referenced any studies for the NZ population. There was an overall lack of empirical evidence as many subgroups are understudied and minimal evaluation of international guidelines affects ability to develop appropriate recommendations for the NZ population. Those involved in provision of care during pregnancy need to understand guidelines to encourage women to be active safely. There was minimal evidence from athletes/highly physically active women. Conclusions: The deficit of NZ based studies of pregnancy and exercise means the relevance of generalised, international recommendations should be more critically examined. Consideration of factors (personalisation, Māori and Pasifika health, specificity and delivery of information) should form the basis of a Delphi approach with health care providers and women in varying stages of childbirth journey to create formal guidelines for physical activity and exercise during pregnancy and postpartum for NZ women. Midwives should work with sports medicine health providers to help create NZ specific physical activity and exercise guidelines for pregnancy and postpartum.
Introduction to go-alongs as a qualitative research method in applied linguistics
(2025-03-24) Chen, Yingqiu; Buckingham, Louisa
The go-along method, a place-based research approach that integrates the strengths of interviews and observations, presents opportunities for exploring the intersections of language and place, such as language use and performance (e.g., people's engagement with the linguistic landscape or people's choice of language in certain contexts or for particular tasks), and language teaching (e.g., situational language teaching, out-of-class language learning, language teaching through linguistic landscapes). Initially developed in sociology and subsequently adopted in other disciplines, go-alongs remain underutilised in applied linguistics research. Grounded in the sociocognitive approach and public pedagogy (out-of-class learning), this study demonstrates how go-alongs can conceptually link language and place by illustrating the three functions they serve: descriptive, pedagogical, and diagnostic (or evaluative). The descriptive function facilitates the documentation of participants’ language use across various places and settings. The pedagogical function supports go-along language teaching by assigning participants tasks tied to specific real-life places, and the data of place-related language use collected during task-doing is developed into materials for future teaching. The diagnostic (or evaluative) function allows for testing participants’ language skills/performances at different places. Go-alongs can also contribute to triangulating interview and observation data, thereby strengthening methodological validity and reliability. Drawing on our two empirical projects that used go-alongs as the primary research tool, we propose a set of procedural guidelines aimed at researchers or practitioners using go-alongs in applied linguistic research. We close with limitations and suggestions for future studies.
