title: Exploring curriculum implications of multimodal literacy in a New Zealand early childhood setting

authors: Haggerty, Maggie

subjects: early childhood curriculum

abstract: Calls to broaden notions of 'literacy' from a focus on print-based and verbal literacies to the incorporation of a range of modes of communication and representation are increasing. This paper uses case study data from 3- and 4-year-olds in a New Zealand kindergarten to explore the affordances offered by different literacies to facilitate communication and learning, and the interplay among literacies. The focus includes verbal, visual and spatial-motoric literacy modes. Several key ideas are discussed: first, that the affordances offered by particular modes may make them better suited to some tasks than others and convey meaning in different ways; second, that use of different modes in combination enhances children's communication and learning; third, that boundaries between traditional and non-traditional literacy modes seem to be permeable; and fourth, that pedagogical discussions with parents can contribute greatly to teachers' understanding of children's favoured literacy modes. Implications include the need for early years teachers to take a broad view of literacies as modes of communication, conceptualisation and meaning-making, so that teachers can notice, support and expand children's favoured modes.

title: Thermal conductivity measurement and prediction of particulate foods

authors: Carson, James K.

subjects: Science & Technology

abstract: There is reason to question some of the published thermal conductivity data for particulate foods. It is argued in this paper, based on thermal conductivity bounds analysis, that the thermal conductivity of particulate foods should range between 0.03 W m⁻¹ K⁻¹ and 0.30 W m⁻¹ K⁻¹ (provided the porosity is greater than 25%), and that any data outside this range should be rejected. This argument was supported by data for five foods measured as part of this study (cocoa powder, corn starch, whole milk powder, sucrose, and wheat flour), and the majority of published data for particulate foods do indeed fall within this range. The geometric model was found to provide the most accurate thermal conductivity predictions of the models considered, and is recommended for use in first approximation predictions.

title: Mātauranga Māori to inform understanding of population dynamics and health of pipi in Waihī Estuary, Bay of Plenty.

authors: Kettle, Tyla

abstract: Estuaries are among the most productive ecosystems on earth. They hold significant value to Māori as they connect the whenua (land), awa (river) and moana (ocean), and are an important source of kaimoana (seafood) including shellfish. However, due to increased anthropogenic pressures, many estuaries are degraded, affecting taonga (Māori treasure) species such as pipi (Paphies australis). My thesis uses kaupapa Māori methodology and is co-developed with Ngāti Whakahemo, tangata whenua (people of the land) of Waihī Estuary. This project fundamentally draws upon mātauranga Māori (traditional Māori knowledge), combined with western science to map the historic and current distribution, abundance and health of pipi in Waihī Estuary; as well as explore the perceptions of threats to pipi and estuary ecology from tangata whenua and the regional authority. 
Participatory mapping was used via kōrero/interviews with kaumātua to identify sites of significance for pipi, which were then sampled in November 2020. Mātauranga ā iwi from Ngāti Whakahemo informed the sampling locations. Previous pipi sampling methodology and protocols undertaken by the Ministry for Primary Industries (MPI) were used to facilitate temporal comparisons of pipi distribution and abundance. Environmental factors including sediment grain size, organic content, total nitrogen (TN) and total phosphorus (TP) were also measured to help understand what drives the population dynamics of pipi. Perceptions of tangata whenua and staff members of the Bay of Plenty Regional Council (BOPRC) were also explored following methods similar to Klain et al. (2018) and implementing a dread risk tool via participatory mapping.
Results show that culturally significant sites identified by kaumātua support high pipi abundances of large size (40mm+), with low abundances of pipi in the upper reaches of the estuary. The inclusion of sites identified by MPI allowed for more comprehensive survey on pipi population dynamics by utilising a stratified survey design. Pipi size and abundance was significantly correlated with environmental factors with high pipi densities associated with medium grain size fractions and low levels of TN, TP and organic content. Over harvesting was perceived by kaumātua and BOPRC staff members as the dominant threat to pipi abundance and Waihī Estuary. Nutrients related to sewage inputs and runoff were rated as the second highest perceived threat and diseased shellfish ranked third by kaumātua and BOPRC staff members. 
This study demonstrates that the sharing of mātauranga ā iwi can fundamentally inform western science methods and can be used as an approach to research in the marine science realm. The research space was shared by researchers and kaumātua, was honourable of the mātauranga, iwi voices were heard and a co-developed field survey plan/research plan was produced. Iwi concerns were made a priority throughout, and incorporated into the monitoring, mapping and management frameworks. Thus, I had a Māori-centred agenda which is important as Ngāti Whakahemo are looking to utilise the results from my research to inform their iwi environmental management plan. This approach will help to strengthen current marine management practices and in turn Aotearoa New Zealand’s ecosystems due to iwi environmental management plans being informed by such results.
