title: Exploring the tension and synergies between science and technology in science education

authors: Jones, Alister

abstract: This chapter explores the way in which technology has been introduced through and by science educators in Australasia in the last 25 years. A number of themes have arisen in this time from using technology to engage students in science, exploring the impact of science on society through technology, considerations of the nature of technology in relation to science, and the exploration and development of technology as a subject in its own right. In this process student and teacher perceptions of technology were explored, as well as teacher change and the influence of teacher/ subject culture through to sustained classroom research and school change and the way in which the introduction of a new subject like technology can influence our thinking around science.

title: Farmland Acquisition and Household Livelihoods in Hanoi's Peri-Urban Areas

authors: Tran, Quang Tuyen

subjects: Farmland acquisition, household livelihoods, Hanoi's peri-urban areas

abstract: While farmland loss (due to urbanisation and industrialisation) causes job losses for a huge number of farmers and threatens food security, it can bring about a wide range of new job opportunities for local people through which they can change their livelihoods and improve their welfare. The literature in Vietnam and some other countries reveals that although there has been much discussion about the mixed impacts of farmland loss on rural household livelihoods, none of these impacts has been quantified thus far. This thesis is the first study to use econometric methods for quantifying the various impacts of farmland loss on households' livelihood strategies and outcomes.
Using survey data from 477 randomly sampled households in 6 communes in a peri-urban district of Hanoi, several regression models were used to examine how and to what extent farmland loss has affected rural household livelihoods in Vietnam. Specifically, three key relationships were considered and tested: (i) the relationship between farmland loss and household livelihood strategies; (ii) the relationship between farmland loss and household livelihood outcomes (income and consumption expenditure); and (iii) the relationship between farmland loss and household income shares by source.
It was found that farmland loss has a positive impact on the choice of non-farm work-based strategies, notably the informal wage work-based strategy. Given the impact of farmland loss, households' income shares actually diversified into non-farm sources, especially informal wage income. Interestingly, the results indicate that farmland loss, coupled with compensation, has no negative impact on livelihood outcomes (neither income nor consumption expenditure per capita). Possibly this can be explained by the fact that a number of households used part of their compensation money for smoothing consumption. In addition, income earned from jobs outside of farming might compensate for or even exceed the loss of farm income due to the loss of farmland. This suggests that farmland loss can have an indirect positive effect on livelihood outcomes (through its positive effect on non-farm participation). 
This thesis makes several key contributions. Firstly, with a combination of an adapted analytical framework and appropriate econometric models, this study provides a proper approach for studies of the relationship between farmland loss and rural household livelihoods. Secondly, it provides the first econometric evidence for the links between farmland loss and household livelihood strategies and outcomes. Finally, based on the empirical results, this study proposes valuable policy recommendations for mitigating negative impacts of farmland loss on rural households and helping them achieve better livelihood outcomes.

title: Ngā tohu o te taiao: Observing signs of the natural world to identify seastar over-abundance as a detriment to shellfish survival in Ōhiwa Harbour, Aotearoa New Zealand

authors: Paul-Burke, Kura

subjects: Tohu

abstract: Māori understandings and experiences of the natural world encompass not only what is known but how it is known, and the intergenerational connectedness of that knowledge with the environments from which it is derived. Ngā tohu o te taiao (hereafter ‘tohu’), or the cultural and environmental signs and indicators of the natural world, are widely used by kaitiaki or local practitioners to identify trends or changes in the state or health of marine taonga (culturally important) species and their associated environments (Paul-Burke, 2017). Māori worldviews position humans within nature and focus on ways in which cultural understandings and intergenerational connections between people and their bio-physical contexts assist in the retention and protection of biodiversity and ecologically sustainable ecosystems (Lyver et al., 2016). Tohu are a fundamental expression of kaitiakitanga or active guardianship and are based on the primal instinct of survival and recognising that in order to survive one must pay attention to the natural signs and signals thoughtfully, so as to manage our mahinga kai (food harvesting area) and ourselves into the future (Paul-Burke et al., 2020). This article considers the example of the over-abundant eleven-armed seastar (pātangaroa, Coscinasterias muricata; hereafter ‘seastar’) predating on culturally and ecologically important shellfish populations in a traditional mahinga kai of Ōhiwa Harbour in the Bay of Plenty region of Aotearoa/New Zealand. The over-abundance of seastars was considered a contemporary tohu of a degrading harbour. It was deemed imperative by iwi (tribe) members that a trial using quantitative methods to investigate predation pressure of seastars on the green-lipped mussel (kuku or kūtai, Perna canaliculus) population be conducted in the harbour. Between September 2018 and February 2019 field trials were undertaken that prioritised mātauranga Māori (Māori knowledge) alongside marine science to assist with a better understanding of the degrading harbour. It was hoped that the research would help and promote recovery, in particular but not limited to, the once abundant but now severely reduced mussel reefs in the soft-mud-bottomed harbour.
