    Mount Taranaki/Egmont occupies a central place in the history and culture of Taranaki people – Maori and European. The mystical qualities of the volcanic mountain have influenced the culture, ecology and landscape history of the area and illustrate that cultural landscapes are often predominantly associative (having powerful spiritual, artistic or cultural associations with a natural element) and broad-reaching in their manifestation within a diversity of cultures. Our human need for a sense of identity and belonging is strongly linked to landscape and place. As Taylor notes [1] ‗Landscape therefore is not simply what we see, but a way of seeing: we see it with our eye but interpret it with our mind and ascribe values to landscape for intangible – spiritual – reasons‘. The mountain itself and the circular ring of protected forest surrounding the mountain– which forms the Egmont National park is a strong example of an associative cultural landscape that embodies both tangible and intangible values. The circle of fertile ring-plain contains and protects the original forest of the mountain which was one of the earliest of New Zealand‘s ecological reserves to be protected and surveyed off from settlement. This circle frames the wilderness of indigenous native forest within the taming grid of a farming culture. The heritage of New Zealand surveying, settlement and forest destruction is poignantly captured in this physical landscape feature and its mystery and symbolism is illustrated in the spiritual beliefs, artistic history and economic products of the inhabitants that live under it. To the indigenous people of Taranaki - Maori, the mountain (Te Maunga) has deeply cultural and spiritual signficance. To Mana Whenua (those with geneological and local tribal authority over the land) the mountain is part of the landscape and an ancestor, it is a reference point and the names and physical features have particular significance as symbols of the people that provide meaning, order and stability. European settlers arrived in the region in 1841 and profound cultural and landscape change resulted. Throughout this time, the mountain appears in imagery and marketing for the area and the conical peak with an idyllic farming scene in the foreground has featured as a regional and national icon represented in art, advertising and symbolism. This paper explores the Maori and European connections to Mount Taranaki as a case study of an associative cultural landscape that has shaped the social and landscape history of an entire region and that continues to influence the future of this special volcanic landscape.

    The high computational cost of the motion estimation module in the new HEVC standard raises the need for efficient hardware architectures that can meet the real-time processing constraint. In addition, targeting HD and UHD resolutions increases the motion estimation processing cost beyond the capabilities of the currently existing architectures. This paper presents a highly parallel sum of absolute difference (SAD) architecture for motion estimation in HEVC encoder. The proposed architecture has 64 PUs operating in parallel to calculate the SAD values of the prediction blocks. It processes block sizes from 4x4 up to 64x64. The proposed architecture has been prototyped, simulated and synthesized on Xilinx Virtix-7 XC7VX550T FPGA. At 458 MHz clock frequency, the proposed architecture processes 30 2K resolution fps with ±20 pixels search range. The prototyped architecture utilizes 7% of the LUTs and 5% of the slice registers in Xilinx Virtex-7 XC7VX550T FPGA.

  • A design methodology for performance maintenance of 3D Network-on-Chip with multiplexed Through-Silicon Vias

    3D integration is an emerging technology that overcomes 2D integration process limitations. The use of short Through-Silicon Vias (TSVs) introduces a significant reduction in routing area, power consumption, and delay. Though, there are still several challenges in 3D integration technology need to be addressed. It is shown in literature that reducing TSV count has a considerable effect in improving yield. The TSV multiplexing technique called TSVBOX was introduced in [1] to reduce the TSV count without affecting the direct benefits of TSVs. The TSVBOX introduces some delay to the signals to be multiplexed. In this paper, we analyse the TSVBOX timing requirements and deduce a design methodology for TSVBOX-based 3D Network-on-Chip (NoC) to overcome the TSVBOX speed degradation. Performance comparisons under different traffic patterns are conducted to verify our solution. We show that TSVBOX-based 3D NoC performance is highly dependent on the NoC traffic pattern and in most simulation scenarios we tried, it shows almost the same performance of the conventional 3D NoC.

    One of the major challenges in the era of big data use is how to ‘clean’ the vast amount of data, particularly from micro-blog websites like Twitter. Twitter messages, called tweets, are commonly written in ill-forms, including abbreviations, repeated characters, and misspelled words. These ‘noisy tweets’ require text normalisation techniques to detect and convert them into more accurate English sentences. There are several existing techniques proposed to solve these issues, however each technique possess some limitations and therefore cannot achieve good overall results. This paper aims to evaluate individual existing statistical normalisation methods and their possible combinations in order to find the best combination that can efficiently clean noisy tweets at the character-level, which contains abbreviations, repeated letters and misspelled words. Tested on our Twitter sample dataset, the best combination can achieve 88% accuracy in the Bilingual Evaluation Understudy (BLEU) score and 7% Word Error Rate (WER) score, both of which are considered better than the baseline model.

  • Can we improve participation in university course surveys using mobile tools? : a practical experiment

    Unitec

    Student course surveys provide an important feedback mechanism for universities. However the quality of this feedback depends largely on the level of participation. New technologies have enabled course surveys to evolve from written paper-based tools to web-based and mobile channels, but using these channels does not necessarily lead to better response rates. This paper discusses the results of a survey designed and administered at Massey University, New Zealand, to gain insights into students’ attitudes towards course surveys and factors that might impact on their participation. The survey also explored the potential interest in mobile channels for providing course feedback. The responses to this survey informed a pilot study that tested a mobile course survey tool. The results of our experiment suggest that, whilst a mobile channel may lead to improved participation, more significant results would depend on its integration into a broader set of strategies and tools for student engagement.

  • Evaluation of a stroke navigation service over a six month period : a mixed method approach

    Wood, Siné (2017)

    Thesis
    Unitec

    AIM: To assess the impact on outcomes of a stroke navigation service for stroke survivors and their families, over a six month period, in comparison to usual care. BACKGROUND: Stroke is a serious health concern and affects both stroke survivors and their caregivers. Caregivers often report feeling inadequately prepared for the caregiving role, lacking information and support, and sometimes experiencing difficulty in communication with health professionals. A stroke navigation service may potentially help stroke survivors and their families through the stroke continuum. Evaluating this service could provide a rationale for implementing the intervention in the New Zealand healthcare system. DESIGN: A controlled mixed-methods intervention study was implemented using a comparison group to evaluate a stroke navigation service from acute rehabilitation services and into the community. METHODS: Convenience sampling recruited six stroke families. Data were collected at baseline, three and six months post-stroke navigation service implementation. Quantitative data were collected using the Modified Caregiver Strain Index, Health Service Use and Short Form-36 questionnaires. Qualitative data were collected using semi-structured interviews and questionnaires. FINDINGS: An over-arching theme of ‘Easing the Journey’ was identified with three themes: 1) Walking alongside, 2) Informing and pursuing avenues and 3) Connecting pathways and bridging gaps. Overall no statistically significant differences were found between groups. CONCLUSIONS: Families using the stroke navigation service felt more supported, informed and found their interaction with health professionals improved with the intervention in comparison to usual care.

    Unitec

    The purpose of this article is to examine how the perceptions of employees could have an influence in business strategy. The problem statement and main research question is: How can employees’ perceptions influence the outcome of business strategy of SMEs in Lao PDR? This article critically reviews the literature pertaining to perceptions and attitudes. Perception involves a sophisticated thinking process, from obtaining data from the external environment, analysing, and converting it through the cognitive process. People’s perceptions of reality have great influence on their behaviour. The significance of this article is: SMEs in Lao PDR can develop better understanding about the influence of employees’ perceptions on the outcome of business strategy. The findings show strong evidence that supports the relationship between employees’ perceptions about strategy and business performance ; employees who had some interest in business strategy accounted for 37%, those with a moderate interest in strategy, 42%, and those very interested in strategy at 16%. Some recommendations are given at the end of the article before the conclusions section.

  • Challenging positional authority : navigating leadership as collaboration

    Turton, Lee-Anne; Wrightson, Helen (2017-05-30T14:30:01Z)

    Journal article
    Unitec

    This article reflects a recent symposium presentation that explored ways positional leadership limits opportunities for members of the community of practice to contribute leading practices. As many early childhood environments in Aotearoa/New Zealand become increasingly market driven, a focus on outcomes and accountability have influenced the leadership and management hierarchy. This focus places leadership as situated in a designated position afforded to one or two individuals (Rodd, 2013). The approach advocated in this article provides opportunities to develop mutually supporting and complimentary shared practices of leading, between all members of the community of practice (Wilkinson & Kemmis, 2016). This aligns with leadership founded on collaboration and empowerment of teachers, as well as student teachers, to contribute expertise and abilities, equating to leading practices. Transformation from individualistic leadership to a more collectivist style, promoting skills and attributes individuals could contribute underpins this approach. A kaupapa Māori model of leadership that aligns with a collectivist perspective, is used to challenge understandings of responsibility within the community of practice. This approach invites communities of practice to draw on people’s capabilities, promote self-efficacy and provide space to grow leaders.

  • Modelling land water composition scene for maritime traffic surveillance

    Background modelling, used in many vision systems, must be robust to environmental change, yet sensitive enough to identify all moving objects of interest. Existing background modelling approaches have been developed to interpret images in terrestrial situations, such as car parks and stretches of road, where objects move in a smooth manner and the background is relatively consistent. In the context of maritime boat ramps surveillance, this paper proposes a cognitive background modelling method for land and water composition scenes (CBM-lw) to interpret the traffic of boats passing across boat ramps. We compute an adaptive learning rate to account for changes on land and water composition scenes, in which a geometrical model is integrated with pixel classification to determine the portion of water changes caused by tidal dynamics and other environmental influences. Experimental comparative tests and quantitative performance evaluations of real-world boat-flow monitoring traffic sequences demonstrate the benefits of the proposed algorithm.

  • Perceptions of community safety in West Auckland and white fragility.

    Unitec and Community Waitakere have recently completed a Lottery’s Foundation funded project looking at the contemporary issues affecting the perceptions of safety in West Auckland communities. A review of eight recent surveys or research reports between 2012 and 2016 into community safety in West Auckland show that the negative perceptions we have about the safety of our community and the people who are part of it, have more impact than the actual amount of crime that is reported in our community. Responses to questionnaires to 159 people covering the age-span, female and male gender, Pākehā/European, Māori, Pacific Island and Asian/other cultures showed that despite a clear fall in reported crime rates in West Auckland people generally believed that crime had increased and was worse than in the rest of Auckland. On a number of different measures, the Pākehā/European participants were significantly more concerned about personal safety and crime that the other communities who did the questionnaire. The Pākehā/European participants were significantly more likely than the other groups to want more police patrols and a get tough on crime approach and were significantly less interested in a collaborative neighbour to neighbour community development approach. The data suggests that perceptions of safety in the community are influenced by culture and that one or more cultures are likely to be seen as the problem by the dominant culture. This raises the issue of the role white privilege (McIntosh, 1988) and, particularly, white fragility (DiAngelo, 2010) in addressing community safety. White fragility explores the challenges of over-reactive white sensitivity to suggestions that their position of privilege might impact on the well-being of people of other cultures

    The use of public funds to host major sport events is a contentious issue that all major cities face. It is expensive to host a major sport event, and the benefits, or lack of, associated with hosting have been widely researched and reported (Kim, Jun, Walker & Drane, 2015; Kim & Petrick, 2005; Ochman, 2013). Therefore, the decision on whether a city should bid to host a major sport event is of critical importance for both the cities elected officials, event owners and organisers, as well as the local community. Community support is considered an essential part of planning an operating a successful event. The perceived social, economic and environmental impact of hosting a major sport event on the local community is commonly used as a method to understand community support for an event. In addition, it is becoming increasingly common for cities to hold a referendum as a method to gauge community support for a major sport event, and as a result decide if the city should submit a bid to host. Competition between major cities for hosting major sport events is becoming increasingly strong. However, Auckland is known as a desirable location to host such events, having recently hosted successfully the 2011 Rugby World Cup, and the FIFA U-20 World Cup and Cricket World Cup in 2015. The possibility of Auckland hosting a future Commonwealth Games provides an ideal context to investigate factors affecting community support for the event, and local resident interest in an eventrelated referendum. A mixed-method approach will be taken to achieve the study’s purpose. The quantitative phase of the research will be a cross-sectional study of local residents in Auckland. To make the results relevant to real world decisions, a representative sample of participants will be surveyed through the use of online market research panels. This phase would measure the perceived social, environmental and economic impact of a future Auckland Commonwealth Games. In addition, this phase would also ask local residents three key questions: 1) Should there be a referendum?, 2) Would you participate in the referendum?, 3) How would you vote in the referendum? Scales with established validity and reliability will underpin the survey. The survey will be designed so that it can be easily replicated in future years to determine if support is changing or applied to other events or stadium developments. The qualitative phase of the research will be semi-structured interviews with key stakeholders that would be involved in a bid to host the Commonwealth Games in Auckland. Interview questions will be formulated based on the results from the crosssectional study of local residents. Data from the interviews will be analysed using thematic analysis.

Green roofs, rain gardens, swales, wetlands, these are all measures that reduce flooding in highly urbanised areas. But what about the design of the city itself? Traditional cities are densely built with buildings and infrastructure. New city plans also follow traditional city plans, a road grid with different zoning areas. The underlying landscape; the topography hydrological patterns, areas of indigenous vegetation, are covered up or destroyed by the new city plan. The result is traditional hydrological patterns are disturbed, existing streams and rivers are piped or culvert. With the paving over of farms, the land losses the ability to absorb rainwater, polluted stormwater is created from the run off with an increase of flooding

    The New Zealand Accident Compensation Corporation (ACC) pays compensation to everyone who is disabled temporarily or permanently by accidents. Accidents include intentional violence received from another person and the costs of such “accidents” run into billions of dollars. ACC is seeking to reduce its liability in this area by funding programmes that that prevent violence. One such programme is Jade Speaks Up a violence prevention programme targeted at 8 to 11 year olds and which over a 6-week period teaches children how to keep themselves safe. This paper describes the programme and the outcomes from the first school in which the programme has been delivered, and shows excerpts from the animated video that is centre-piece of the programme ACC is funding a trial of this programme which will be delivered to nine intermediate level schools involving 1250 children and over 40 teachers. The evaluation involves both experimental and control groups, pre- and post-tests, a six-month follow-up and a switch of the control group to the experimental condition at the beginning of the subsequent term. The evaluation includes two standardised tests of child well being (the Center for Epidemiologic Studies’ Depression Scale for Children, Weissman, Orvaschel, & Padian, 1980; and the Child Outcomes Rating Scale, Duncan, Miller & Sparks, 2003). and measures of learning, practice and programme engagement. Teachers as well as students are participants. Preliminary results show that children on the Jade Speaks Up programme make significant gains at post-test in the well being tests compared to pre-test and compared to the control group The children overwhelmingly felt the programme was interesting, useful and fun. Teachers were also positive about the programme. Still to come is the 6-month follow-up where we will be able to see whether the skills and knowledge taught have been used and the well-being gains sustained.

    As the largest urban region of New Zealand, Auckland is well known for its unique lifestyle with a clean, green environment. However, rapid urban growth and horizontal urban sprawl is threatening the very lifestyle that the world and Aucklanders value so much. This paper discusses the development of a green space network along State Highway One, the growth corridor of the Auckland region. The authors established two sets of criteria, environmental and social, to drive the development of the network. Three case studies were developed to test the proposition, ranging in scale from the regional to the local. Research findings suggested that preserving and enhancing a green network in the greater Auckland Region could not only offer a new regional park system, but also provide more land for sustainable urban growth and enhance the quality of life for future citizens.

  • Creating inclusive environments and catering for individual needs

    Journal article
    Unitec

    In early childhood education (ECE) settings teachers need to be conscious conscious of the diverse learning needs of children in their care. Meeting individual needs has roots in the rights discourse which aims to promote human rights, social justice and inclusion, removing barriers that may hinder learning for children with diverse needs. As the population becomes more and more diverse ECE teachers are challenged more and more in their daily practice. In response to the increasingly diverse needs of young children, teachers are continually trying to incorporate inclusive practice. However for various reasons, some ECE settings may find this difficult and this may be due in part to society's negative attitude towards difference. Perhaps the biggest challenge teachers face today is dealing with issues of inequities. We propose that education be more focussed on promoting an understanding of diversity and difference where educators understand each individual learner. In promoting social justice, strong advocacy is called for to meet individual needs in early childhood settings. Through a framework of inclusive education, this article discusses some existing challenges and presents ideas on how early childhood teachers could promote equity and social justice in their settings.
