title: Multiple reading: text and theory

authors: Moffat, Kirstine

subjects: English

abstract: It was with great pleasure that I accepted an invitation to run a workshop at the recent NZATE Conference. The topic of my session was an overview of the use of literary theory in the teaching of English and that same focus directs this written version of my presentation. I approach this topic not as a theory guru or expert, but as a practitioner who has found that an understanding and application of theory has made me a better teacher. In particular, I believe that judicious use of theory enables me to communicate to students the diverse ways in which written and visual texts can be read, encouraging them to think for themselves in a fresh and original manner and to see points of connection between a range of texts. Combined with the essential critical tools of close reading and textual analysis and support, a knowledge of theory helps students to think critically and to shape informed, coherent arguments.

title: Understanding and ameliorating non-linear phase and amplitude responses in AMCW Lidar

authors: Godbaz, John Peter

subjects: phase linearity

abstract: Amplitude modulated continuous wave (AMCW) lidar systems commonly suffer from non-linear phase and amplitude responses due to a number of known factors such as aliasing and multipath inteference. In order to produce useful range and intensity information it is necessary to remove these perturbations from the measurements. We review the known causes of non-linearity, namely aliasing, temporal variation in correlation waveform shape and mixed pixels/multipath inteference. We also introduce other sources of non-linearity, including crosstalk, modulation waveform envelope decay and non-circularly symmetric noise statistics, that have been ignored in the literature. An experimental study is conducted to evaluate techniques for mitigation of non-linearity, and it is found that harmonic cancellation provides a significant improvement in phase and amplitude linearity.

title: Hidden hunger in a land of plenty: Food insecurity in Aotearoa New Zealand

authors: Graham, Rebekah Sarah

subjects: children, food, Māori, material hardship, scholar-activism

abstract: Aotearoa New Zealand is a relatively wealthy, food-producing nation. Yet, increasing numbers of the populace are experiencing food insecurity, hidden hunger, and material hardship. More than an individual issue, ensuring food security requires consideration of the social and cultural components of growing, preparing, and consuming food and meals. Access to sufficient food to eat and the surrounding social practices are central to human flourishing. This article documents three research exemplars that challenge dominant global representations of Aotearoa New Zealand as an idyllic haven. Each case explores the invisibility and downplaying of hunger and poverty that occur within this ‘land of plenty’. In describing and reflecting our respective research projects we illustrate how broader socio-political and economic factors play out materially in the everyday lives of marginalised groups by restricting access to food. Given that community psychologists have values which necessitate a critical praxis, we have the responsibility to challenge power differences and practices based on historical perceptions that serve to maintain inequities.
