title: Scheduling contractors' farm-to-farm crop harvesting operations

authors: Basnet, Chuda

subjects: harvesting

abstract: The harvesting of renewable resources from an operations scheduling viewpoint is introduced, and a harvesting scenario arising in the agricultural context involving a commercial contracting enterprise that travels from farm-to-farm harvesting crops is discussed. This paper is an extension of previous work by two of the authors from the one-farm to the multi-farm case. In both cases, the duration of each operation is dependent upon the combination of constrained resources allocated to it, equipment and worker allocation is restricted, and minimum or maximum time lags on the start and completion of operations may be imposed. The present case incorporates harvesting at more than one farm and thus the sequence in which the farms are visited and the inter-farm travel times must be taken into account. We report on a harvesting scheduling model and solution procedures designed specifically for large-scale versions of the multi-farm case. The computational times experienced in solving general instances of the model of small-to-medium practical size by a commercial integer programming package are encouraging. Greedy and tabu search heuristics, which are capable of solving problems of relatively large dimensions in reasonable computational time are also included. The authors believe that the model and the solution techniques developed represent a useful addition to the farm crop contractor's tool kit.

title: Improving compliance and on-task behaviour with a self-management intervention within a mainstream school.

authors: Higgs, Alice

subjects: compliance

abstract: Compliant behaviour is a key skill related to the social and academic success of children. Extending the research conducted by Lee (2016), the goal of this study was to evaluate the effectiveness of a technology-based self-management intervention on the compliant behaviour of two typically developing 10-year-old boys. Students each used an iPod Touch (6th generation) with iOS 12.2 and an inbuilt message notification system to receive visual prompts from the researcher, prompting them to record their behaviour on an application. The application 'StickerPop! Sticker Charts' was used by each of the participants to self-record their compliant behaviour. The effect of the intervention was assessed within a multiple baseline across participants design, incorporating a reversal design. Results indicate that the intervention was highly effective in increasing compliant behaviour for both participants. Concomitant improvements in on-task behaviour were also observed for one participant. These results were maintained during a two-week follow-up. The intervention was judged highly acceptable by the participants and their teacher. Overall, the intervention was effective within a classroom environment over a relatively short amount of time, benefiting the teacher and students. Strengths, limitations, and the theoretical implication of this study are discussed. Future research is suggested.

title: Takitoru: creative practice toward the development of a trilingual dramaturgical kaupapa

authors: Lodge, Alexandra Rose Pittaway

subjects: theatre

abstract: I have focused on writing a play in the three languages of Aotearoa: New Zealand Sign Language, te reo Māori, and NZ English. Through the development of this script with three actors I have found techniques for performance and workshopping to encourage multilingual creative practice for a playwright. Through case studies of playwrights doing similar work at an international level, I have synthesised analytical and creative research into a final script and summary of my dramaturgical findings.
Through creative practice in scriptwriting and developmental workshops, this research explores what story-telling modes, devices or styles seem particularly apt for conveying an inclusive and engaging trilingual narrative on stage.
This specifically involves developing a dramaturgical set of insights for others who may want to do cross-language performance in Aotearoa.
