    Improved efficiency in growing and converting pasture into product is required to maintain New Zealand’s competitive advantage in dairying. This study focused on two areas of grazing management, the first an assessment of the indicators leaf stage, pre-grazing yield and grazing residual. In summary, 49% of measured paddocks were grazed too soon based on leaf stage, 62% were grazed outside the recommended pre-grazing yield, and 48% of measured paddocks were not grazed to a desirable height. The second part of the study provided an insight into farmer decision making at an operational level of grazing management with three key components identified. These were: 1) The recruitment of paddocks into a grazing plan; 2) The shuffling of the paddock grazing sequence within the grazing plan; and 3) The management of individual grazing events before, during and after the event. An improved understanding by rural professionals of grazing management decision making would result in extension strategies which generate increased farmer engagement, adoption of grazing management technologies and improved on-farm productivity.

    Unitec

    This paper promotes active oMTL (i.e., Online Multitask Learning with task selection) by proposing two smart task ordering approaches: QR-decomposition Ordering and Minimal-loss Ordering, in which the optimal sequence of tasks for oMTL is computed as the training data/tasks are being presented. Our experimental results on four real-world datasets show that the proposed task orderings outperform all existing task ordering approaches to active oMTL.

  • Improving learning outcomes by designing engaging educational tools

    Casey, John; Baghaei, Nilufar; Nand, Kalpana (2014)

    Conference paper
    Unitec

    The success rate of computer games in engaging children has prompted educational researchers to investigate if similar techniques can be used to engage children with learning. In this paper, we present the results of a study conducted with 120 primary school children, in which two versions of our proposed educational tool (Features Enriched Game (FEG) vs Feature Devoid Game (FDG)) were used for four weeks to teach primary school curriculum areas of Numeracy and Te Reo Maori language. The effectiveness of the educational tool was measured using a pre-test and a post-test, as well as the frequency and duration of time on playing the game. The results showed that the FEG version enhanced children's learning - it was more effective as an educational tool in both Numeracy and Te Reo curriculum areas, when compared to the FDG version. In the case of Numeracy, the increase in scores was twice as much as the FDG version and in the case of Te Reo (Maori Language) it was five times as much. Similar results were also shown by other indicators such as time and frequency. Finally, the results showed that the

  • Effects of seasonal growth rings on the microwave measurement of wood

    Holmes, Wayne; Bogosanovic, Mirjana; Emms, Grant; Mukhopadyay, S. (2014-09)

    Conference paper
    Unitec

    In order to determine more accurate indicators of wood structure obtained by microwave sensing and improve our understanding of plane wave propagation through this complex material, we have undertaken a permittivity survey and experimentally investigated scattering of a plane wave, measuring its transmission over two non-parallel surfaces of a rectangular lumber sample. This novel non-destructive testing technique offers results which may significantly contribute in a more accurate propagation modeling and industrial wood quality testing.

    Fifteen years of groundwater quality monitoring in the Kapiti Coast by the local authority in Wellington, New Zealand, has identified an area of elevated nitrate concentrations in the Te Horo area, with some monitoring bores testing for concentrations above 5 mg/L. However, recent analysis seems to indicate that contaminant levels have decreased from what was previously recorded, although still remaining elevated. The purpose of this study is to investigate if changes in nitrate concentrations over time were significant, and, if so, determine which factors have contributed to these changes. Initial temporal trend analysis indicated that nitrate concentrations since 1993 have decreased in the majority of monitoring bores. Tobit regression analysis was subsequently undertaken using several land use, land cover, soil type, climate and chemical explanatory variables. Results indicated that beef cattle farming, fruit growing, settlements and lifestyle blocks were associated with increased nitrate concentrations. Groundwaters higher in dissolved oxygen which underlie fine sandy loam soils (which are highly permeable soils) were also identified as been susceptible to higher nitrate concentrations.It was ultimately determined that the temporal decrease in concentrations is best explained by improved land use practices as physical characteristics and land cover overlying groundwater had not changed substantially and thereby explaining the decreasing trend in nitrate concentrations.

    Massey University

    Research ‘through’ design is a becoming’ field, which presents a challenge to designer/researchers. Recently, national research authorities have broadened their parameters to validate creative work in art, architecture and design. This study and the resulting model test the perceived ambiguity of the requirements provided by Australia’s Excellence in Research for Australia (ERA) and New Zealand’s Performance-Based Research Fund (PBRF) for creative works to be recognised as research through exhibition, and proposes a peer-reviewed model for interior design/interior architecture that can provide appropriate quality assurance processes for creative works.

  • BRIEF COMMUNICATION: The potential of the New Zealand goat industry

    Carr, AJ; Schreurs; Lopez-Villalobos; Thomas, D; Tozer, PR

    Conference paper
    Massey University

    The New Zealand goat industry is evolving and there is potential for expansion of its export products. The production and value of the New Zealand goat industry has been explored previously when the industry was in its infancy (Sheppard & O’Donnell 1979), at a time when Mohair production was seen to be ‘the most profitable goat farming enterprise’. Since then major expansion has occurred in the production and export of dairy-goat products, and the production of quality Boer goat meat is under consideration. In order for further progress to be made, knowledge of the current production levels and value of the goat industry, and its potential for expansion is required. Using information describing the current situation of the goat industry (Scholtens et al. 2017) and the value of the goat (Lopez-Lozano et al. 2017), a model was created to estimate the current and potential production and value of the New Zealand goat industry by 2025.

  • Deployment of hydrogen technologies in New Zealand

    Leaver, Jonathan; Gardiner, A.; Spencer, J. (2017-07-11T00:07:32Z)

    Conference paper
    Unitec

    In 2013 the implementation in New Zealand of hydrogen technology took a significant step forward when the private sector company H2NZ facilitated the establishment of a nationally focused Hydrogen Technology Development Committee (HTDC) based at Unitec (NZ) to provide commercially viable renewable hydrogen based energy solutions. The scope for deployment of hydrogen technologies initially encompasses transport, stationary equipment and heating. A New Zealand Branch of the International Hydrogen Energy Association will be established as a promotion and information dissemination entity. Concomitantly commercial activities are being managed by H2NZ; education and research by Unitec; and expert advice and facilitation of commercialisation by Callaghan Innovation, a government agency. Industry partners are engaged at all levels to maximise potential for commercialisation. In December 2013 H2NZ through the HTDC launched the development of two projects. These are a hydrogen powered quad bike and a zero grid energy residential house incorporating on-site hydrogen storage. Both are planned to be built by the end of 2014. In addition H2NZ is facilitating the commercialisation of UniSyD techno-economic system dynamics modeling software through collaboration between the joint intellectual property owners Unitec and the University of Iceland (UI), and the New Zealand National Energy Research Institute.

  • A survey on Internet usage and cybersecurity awareness in students

    Tirumala, Sreenivas Sremath; Sarrafzadeh, Hossein (2017-06-01T14:30:09Z)

    Conference paper
    Unitec

    There has been an exponential increase in the usage of the internet, particularly among students since the introduction of e-learning and Bring Your Own Device (BYO) initiatives into the education system. In New Zealand the percentage of the population using the internet is now 93.8% and this increase in internet usage has increased the risk of cybersecurity attacks This makes it necessary to provide awareness and education on cybersecurity to students who are potential targets for exploitation. However, to provide this awareness it is necessary to understand what their current knowledge on cybersecurity is which forms the basis of this paper. This paper presents the results of a survey conducted on internet usage and cybersecurity awareness among three age groups between 8 years and 21 years. A questionnaire consisting of various questions on internet usage and cybersecurity concepts was prepared. For this survey, we considered both computers (desktops & laptops) and mobile devices (tablets & smartphones). The results of the survey showed that cybersecurity awareness among the surveyed students was generally low with the lowest level in the 8- 12-year age group. The students of 8-12 age group were able to answer only 19% of survey questions. Furthermore, most of the students were not familiar with common cybersecurity terms and did not demonstrate enough awareness of common threats such as phishing. The results further show that the majority of the students were not aware of cybersecurity tools for tablets and smartphones which are frequently used devices for BYOD. The key contribution of this paper is to emphasize the necessity to create cybersecurity awareness among students.

    As we all know, human vision is quite sensitive to abnormal behaviors, which is attributed to the discharging of the receptor cells in the brain visual cortex and the ensuing bioelectrical energy features. Inspired by this biological nature, this paper constructs a computing model to describe video dynamic energy, which can further improve the perception of machine vision to abnormal behaviors. Experiments show that this computing model can extract video energy features of abnormal behaviors under complex environment.

    With an overall huge amount of water available in Tahiti, we might think that future generations have no reason to worry; however, this is not reflecting the real aspect of water availability in each district. By analysing the situation and the spatial distribution of the current water available, problematic areas have been identified. The methodology considers the major current characteristics, such as geographical variations for rainfall patterns and water distribution, but also demographic variations and distribution over the area. There are 3 types of situation identified: In Papenoo: where water is available in a really huge amount with about 200 millions of cubic meter discharged per year, which is way higher than water demand in that area In Afaahiti: where they are actually having sufficient water discharged by the AOMA’s river, but are likely to experience water shortage in the future, with a minimum storage required volume of 2,300,000 m3 by 2050 In Papara: where the most critical situation is found, especially during the dry seasons, with an actual water deficit requiring a minimum storage volume of 760,000 m3 .Also infiltration volume of about 730,000,000 cubic meters recharging the underground reservoirs per year is found for the whole island.

    Group abnormal behaviors often occur abruptly under video surveillance, thus bringing serious consequences. How to recognize these behaviors correctly has always been the difficulty in research on intelligence video surveillance. This paper is based on the basic theory of Markov Random Fields to extract the features of those in video images, so as to recognize the group abnormal behaviors under video surveillance. Experiments show that this method can well reflect the real situation at the spot.

    The term personalized learning has proliferated over recent years especially with the advancement of several educational technologies, conceptual frameworks and mobile and wireless internet technologies. This paper investigates to identify most acceptable personalised learning paradigm for educators. A detailed literature review on various aspects of personalized learning is also presented. Eleven participants with moderate to highly-experienced in teaching across eight countries took part for this study. The data is collected via LinkedIn collaborative participation eliminating the possibility of bias towards a particular outcome. This provides both theoretical and empirical aspects of the topic in question. Interview data was analyzed using content analysis techniques to group issues raised by the participants into emerging themes. This paper concludes with acknowledging the necessity of good combination of teaching and technology for a successful personalized learning paradigm.

    Mobile games can be effective, evidence-based, and motivating tools for the promotion of children's health. Traditional method for diabetic education relies heavily on written materials and there is only a limited amount of resources targeted at educating diabetic children. In our earlier work, we proposed a novel approach for designing computer games aimed for educating children with diabetes. In this paper, we apply our game design to a mobile Android game (Mario Brothers). We also introduce three heuristics that are specifically designed for evaluating the mobile game, by adapting traditional usability heuristics. The results of a preliminary evaluation study, conducted for a week, showed that the children found the game engaging and it helped enhanced their knowledge of healthy diet and lifestyle.

  • Flipping research : a model for future focused research making learning visible in health and physical education

    McKay, Anne; Bowes, Margot; Thompson, Kylie (2015-04)

    Conference paper
    Unitec

    This paper reports on a future-focused model for practitioner-led inquiry (PLI) in secondary Health and Physical Education (HPE). As a future-focused model this paper draws the notion of the Flipped Classroom (Tucker, 2012), where teacher’s front end the development of their inquiry questions with the support of tertiary academics who review the literature and suggest appropriate methodology to support the teachers’ research, while simultaneously addressing the tension for teacher educators to conduct research as a significant output of academic work. The purpose of the study is to make student learning more visible to students, their families (whānau) and to make this learning as explicit to both of these groups as it was to their teachers. The paper describes concerns raised by teachers that students found it difficult to identify their learning in Health and Physical Education (HPE) and consequently the students could not recognise next steps for future learning. This concern became the focus of the inquiry approach in two large metropolitan city schools; a traditional subject specific HPE delivery school and a school with a future-focused integrated subject curriculum. The study used a collaborative action model where both students and their whānau were asked what students actually learn in HPE, how they learn and how they know they are learning? As co-researchers with teachers, the authors believe that if students and their whānau are able to recognise what they are learning and how they are learning it becomes a more realistic goal for them to jointly consider, where are the next steps in their learning are. This puts students more on the path to being self-regulating and lifelong learners. As the co- researchers we argue that by making the metacognitive process of learning visible in HPE contexts, beyond teachers to students and their whānau, the Vision of the New Zealand Curriculum (NZC) (Ministry of Education, (MOE), 2007) of Twenty First Century (21C) learners as highly confident, connected, actively involved, lifelong learners, may be better actualised.
