Using data from multiple waves of the Growing Up in New Zealand longitudinal cohort study, children's musical engagement was assessed across five activity domains: singing, listening to music, watching videos (including music), music activity participation, and attending music events. Engagement in each domain was categorised into four participation levels: None, Short-term, Repeated, and Sustained. Longitudinal patterns were assessed with Sankey plots, and ordinal regression was used to predict engagement levels from socioeconomic variables, including maternal education, household structure, household income, gender, ethnicity, disability status, area-level deprivation, and rurality. Our results show that engagement patterns shifted with age, with family singing decreasing and individualised music listening and video watching increasing over time. Gender, ethnicity, and socioeconomic variables were key predictors of sustained engagement across activity domains. Children's musical engagement trajectories varied widely and were influenced by both individual characteristics and modifiable contextual factors. These findings highlight the need to consider equity of access and cultural relevance when supporting musical participation across childhood in New Zealand.</p>","PeriodicalId":520341,"journal":{"name":"Journal of the Royal Society of New Zealand","volume":"56 1","pages":"e70017"},"PeriodicalIF":2.1,"publicationDate":"2026-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12965002/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147380289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design integrates the flexibility of a rectangular resonator with the high quality factor characteristics of circular cavities. By constructing SIW resonators with a hexagonal geometric configuration and combining a three-cell cascaded structure with cross-coupling theory, transmission zeros are introduced at the passband edges to regulate the electromagnetic field distribution. A duplexer is designed and fabricated for center frequencies of 6.8 and 7.9 GHz, with relative bandwidths of 3.5% and 7.5%, respectively. The measured results show that the isolation between passbands reaches -55 and -43 dB, the out-of-band rejection is better than -40 dB, and the measured results are in good agreement with the simulation results. This scheme combines the advantages of low radiation loss, high power-handling capability of SIW structures, and the integration advantages of planar technology, providing a new path for the design of high-performance duplexers in microwave and millimeter-wave frequency bands.</p>","PeriodicalId":520341,"journal":{"name":"Journal of the Royal Society of New Zealand","volume":"56 1","pages":"e70023"},"PeriodicalIF":2.1,"publicationDate":"2026-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12965003/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147380440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We asked 180 members of the public to write the same short phrase in all eight configurations and to rank their writing from clearest to least clear.

Our analysis shows that the significant factors affecting clarity are the hand used for writing and the orientation of the surface, while grip size does not affect clarity.
