  • Increasing capacity at Monarch Wildlife Cruises and Tours: a case study approach

    Keenan, Victoria (2004-02)

    Report
    University of Otago

    Monarch Wildlife Cruises and Tours is a small eco-tourism business providing tours of the Otago Peninsula and an unrivalled wildlife cruise around Taiaroa Head. This company has continued to grow since its inception in 1985, but faces serious capacity constraints in the land transport aspect of its business. The purpose of this research is to examine options available to the company to increase their land transport capacity; the aim is to evaluate each option and recommend the most appropriate forward focus for the business. The research was conducted using a single case study methodology and involved four stages. These stages included a review of the academic literature, semi-constructed interviews, the collection of data through company documentation and observation as well as various discussions with potential organisations that lease and sell buses. Seven options for increasing the transport capacity of the company were investigated in this research. These were: staying with the status quo, withdrawing the transport from the tours, buying an additional bus, selling their van and buying or leasing an additional bus, selling all the vehicles or leasing them on long - term contracts. The last option investigated in this research was contracting all transport facilities to another party. Each option was analysed on cost, practicality, and its overall effect on the business. The benefits and disadvantages of each option were also discussed and contributed to the final decision. It is recommended that the transport aspect of the business be contracted out to another party. Further investigation will be required to determine the most appropriate organisation to contract to. Further work will also be needed to define the terms of such an agreement. However, at this stage Malcolm Budd from the Otago Explorer seems to meet all requirements. The recommended option was chosen because of its propensity to be cost effective and provide benefits that would outweigh cost. The disadvantages of this option were found to be minimal in that they would not adversely affect service quality or the core operations of the business, which is wildlife cruises. Lastly, the recommendation effectively increased the company's transport capacity and proved to be advantageous over the long term. Secondary recommendations included decreasing prices in the winter months to encourage people that might not otherwise purchase the tours; that the number of free of charge passengers be reduced in order to make room for paying customers, and to further manipulate demand and supply by allowing employees to leave secondary tasks till quieter periods, when the business is busy. The company also has the potential to diversify into other areas and increase customer involvement in the service delivery process by allowing customers to book and pay their tours on-line.

  • Nutrient Budget for Lakes Rotoiti and Rotorua. Part I: Internal Nutrient Loads

    Hamilton, David P.; Alexander, Will; Burger, David F. (2004)

    Report
    University of Waikato

    Time series data of temperature and concentrations of dissolved oxygen and nutrients (total nitrogen – TN, total phosphorus – TP, nitrate – NO³, ammonium – NH₄ and filterable reactive phosphorus - FRP) were examined for trends in Lake Rotoiti for 1981-82 and 1990-2003 and in Lake Rotorua for 2002-03. TP, NO₃, NH₄ in bottom waters (40-60m) of Lake Rotoiti, below the thermocline, were examined using regression equations to quantify seasonal transformations of TP, NO₃ and NH₄. There is a relatively linear build-up of phosphorus through time in the hypolimnion following the onset of stratification and initiation of deoxygenation until the time of winter mixing. When there were high frequency nutrient data for Lake Rotoiti (1981-82 at 60 m, 1991-94 at 60 m and 2001-02 at 40 m depth) the rate of seasonal phosphorus build-up could be quantified by regression to within a relatively narrow range of 111 mg TP m⁻³ yr⁻¹ (0.304 mg TP m⁻³ day⁻¹ ) in 1992-93 to 136 mg TP m⁻³ yr⁻¹(0.373 mg TP m⁻³ day⁻¹ )in 1981-82. Based on the first and last points of all the regression equations developed for TP increase, approximately 14.4 (1993-94) to 20.5 tonnes (2001-02) of phosphorus may be added to the hypolimnion of Lake Rotoiti during stratification. There is no evidence of a consistant interannual change in the seasonal build-up of phosphorus over the years considered and the reasons for interannual variations in the rates are not immediately apparent.

  • Social Dimensions of Sustainable Agriculture: A rationale for Social Research in ARGOS

    Hunt, Lesley; Campbell, Hugh; Fairweather, John; McLeod, Carmen; Rosin, Chris (2004)

    Report
    University of Otago

    As the rationale for the social research objective within ARGOS, this document provides a preliminary discussion of the theoretical and methodological approach being taken by the social researchers in the project. As such, it articulates the ‘social corner’ of the research and details the approaches and issues that we consider central to a social scientific analysis of agricultural sustainability.

  • Social Research Compendium: Key Questions on Social Dimensions of Agricultural Sustainability

    Campbell, Hugh; Fairweather, John; Hunt, Lesley; Mcleod, Carmen (2004)

    Report
    University of Otago

    Following on from the Social Research Rationale, this document takes the rationale an important step further by developing a list of key research topics (and specific issues) that form a comprehensive list of research items that the Social Objective consider to be of interest. Three general instructions are useful before going further into this document. 1) A comprehensive list of research topics is necessarily big. Like Objective 4, the general research process for Objective 5 is to start broad and use the first two years of data gathering to refine the topics down to a more focused set of issues and foci. 2) The topics are positioned to answer five very broad questions about our ARGOS farms: • Who are they? Describe the sociological characteristics of the participating farmers, households and enterprises. • What do they think? What is the positioning (or key ideas) of our participants in terms of a list of core concepts in the project? • What is their capacity to act? Even if people think a particular way, or want to do some things, individuals are nonetheless constrained in many ways. Social scientists consider this key issue to be central to any analysis: their capacity to act. • What changes over the period of the project (and in retrospect)? Both looking back in time, and through the period of the project, what are the key dimensions of change in the farms? • What are the key influences on these changes? What the key processes and ‘sites of action’ that influence farm activity, and which can assist us in understanding how more pro-active intervention to achieve change might be undertaken? 3) What gaps are left? This document contributes to getting all the different researchers around the Social Objective clearly aligned and coordinated in framing up and delivering the next phase of research. It also helps to very clearly define the interests and foci of the social research for the other participants in ARGOS. However, maybe its most important task is to provide an opportunity for discussion around those points of interest that Objective 5 shares with the other Objectives, as well as where there are significant gaps as yet unaddressed by the project.

  • Optimising child accident research outcomes: An action research project on maximising the dissemination and implementation of the Summer Research Scholarship Project reports and recommendations of the Child Accident Prevention Foundation of New Zealand

    Smith, Nicola Kiri; Cowley, Natalie Anne; Horgan, Brett; Swain, David (2004)

    Report
    University of Waikato

    A key objective of the Child Accident Prevention Foundation of New Zealand (hereafter referred to as "CAPFNZ" or "the Foundation") is to reduce the incidence and severity of child accidents. The reports and recommendations that arise from the Foundation's Summer Research Scholarship (SRS) projects have the potential to be a major means to achieving this end. The purpose of this research was to investigate the extent to which the SRS projects were achieving that objective, by assessing the degree to which CAPFNZ SRS reports and especially their recommendations are currently in the public domain. The research also identified the current barriers or obstacles to dissemination, and determined cost-effective ways in which dissemination and implementation of these reports and their findings could be enhanced. Our proposal foreshadowed the prospect of this project yielding a demonstration website as one approach to achieving a more effective distribution of CAPFNZ SRS reports and related material.

    Ashwell, Allanah; Ridley, Sally Fenwick; Thompson, Keri (2004-02)

    Report
    University of Waikato

    In response to the needs of Maori informal carers, a training programme was developed for whanau carers in the Waikato region. It was delivered by LIFE Unlimited. It is a unique training programme in that it is community driven and focuses on informal caregivers who are Maori. The overarching aim of the whanau carers training programme is to provide increased training and support of informal carers. This report aimed to evaluate the effectiveness of the whanau carers training programme, including: the unique nature of the programme, the critical success factors, the barriers to success if any, and suggested improvements. The report concludes the programme has had a positive and definite impact upon the whanau carers. The evaluation team observed that the overall programme works very well and fulfils its stated obligations to the Ministry of Health. The programmes are delivered well, and are well received by the client group.

  • Boat electrofishing survey of Te Weta Bay, Lake Rotoiti

    Hicks, Brendan J.; Ring, C. Alex (2004)

    Report
    University of Waikato

    We used New Zealand’s first successful electrofishing boat to survey fish in Lake Rotoiti, North Island, New Zealand, principally in Te Weta Bay. The primary objective of the fishing was to see if undesirable fish species such as koi carp (Cyprinus carpio haemaotopterus; Zhou et al. 2003), brown bullhead catfish (Ameiurus nebulosus), and rudd (Scardinius erythophthalmus) have become established. Circular excavations were seen in the lake by a NIWA SCUBA diver in late 2003, and these were similar to nest excavations associated with catfish in other locations. The native fish common smelt (Retropinna retropinna) and bullies (Gobiomorphus sp) were caught, with a few goldfish(Carassius auratus). Poor water visibility made observations difficult in some parts of the lake, especially on the southern shore and in the outer part of Te Weta Bay closest to the main lake. Fish densities ranged from 2.3 to 11.7 fish 100 m⁻². These should be regarded as minimal densities because the electroshoked fish were counter from the boat but mostly not retrieved; also, only a single pass was conducted. No recognised pest fish species were caught, but we cannot exclude the possibility that pest fish might occur at sites that were not fished. No trout were caught, possible because of the high water temperature (22°C).

  • Boat electrofishing survey of Apata Pond and Lake McLaren

    Hicks, Brendan J.; Bell, Dudley G.; Ring, C. Alex; Tempero, Grant Wayne (2004)

    Report
    University of Waikato

    We used New Zealand’s first successful electrofishing boat to catch koi carp (Cyprinus carpio haemaotopterus; Zhou et al. 2003) and rudd (Scardinius erythophthalmus) at two sites in the Bay of Plenty, North Island, New Zealand. Five large koi carp were caught in a pond near Apata; shortfinned eels and adult inanga were also caught. In Lake McLaren, a small hydro-electric impoundment on the Wairoa River, two rudd were caught; longfinned eels (Anguilla dieffenbachii), common bullies (Gobiomorphus cotidianus), and brown and rainbow trout (Salmo trutta and Oncorhynchus mykiss) were also caught. Low ambient conductivities (43-90 µS cm⁻¹) is likely to have restricted the electrofishing field and power transfer to the fish, but fish capture was still successful. Clear water compensated somewhat for the reduced effectiveness of the field. Fish densities were low at both locations. The minimum fish density was 0.31 fish 100 m⁻² in the pond at Apata, and 0.61 fish 100 m⁻² in Lake McLaren. These should be regarded as minimal densities because only a single pass was conducted. All the koi carp caught in the pond at Apata were 521 to 564 mm fork length and all were 8 years old; there were two males and three females. One female was about to spawn; however, no other koi carp were found, so breeding appears to have been unsuccessful in this habitat. The two rudd from Lake McLaren were 203 and 240 mm fork length 6 and 7 years old respectively. Thought no younger age classes were caught, we cannot exclude the possibility that rudd could reproduce successfully in Lake McLaren.

  • Disabled Māori and disability support options

    Nikora, Linda Waimarie; Karapu, Rolinda; Hickey, Huhana; Te Awekotuku, Ngahuia (2004-01-01)

    Report
    University of Waikato

    The goal of this research project was to provide information to enhance the development and implementation of an effective model of disability support service provision to Maori with disabilities. This was done by identifying and documenting the needs expressed by disabled Maori and their carers living in the Midland area, and by considering the experiences and observations of a key informant group. From our reading of the literature and the feedback we received from participants, a proposed model of disability support service provision has been proposed. In five sections, this report begins by defining disability, and also by defining the act of caring for the disabled. Focussing on the Maori experience, obstacles, access to existing support services, cultural barriers, and health policies are discussed. In the second chapter, the research methodology is described, along with how the information was gathered. Following this is the third section which presents the opinions and reflections of Maori with disabilities. It concludes strategically with a view of the ideal community, suggesting possible resolutions, by exposing current flaws and inadequacies. Chapter four records the views and perspectives of key informant/whanau carers who participated in the project. They offer an insightful account of the often unrecognised side of the disability experience. Considering the preceding discussions, the final section develops a model of service provision for Maori with disabilities, and proposes this for effective service delivery.

  • Planning and governance under the LGA: Lessons from the RMA experience.

    Borrie, Nancy; Memon, Ali; Ericksen, Neil; Crawford, Janet (2004-06-01)

    Report
    University of Waikato

    The purpose of this report is to identify ways in which experiences gained from the RMA as a devolved and co-operative planning mandate can enable local and central government and other stakeholders to more effectively implement the LGA. The report is based on findings from the FRST-funded research programme on Planning under Co-operative Mandates (PUCM). We argue in this report that the experiences gained from the RMA can inform effective implementation of the LGA in three important respects: Preparation and implementation of LTCCPs; The community consultation process for formulating community outcomes; and Māori participation in planning and governance.

  • Prostate cancer screening in New Zealand

    Logan, R; Fougere, G; Hague, K; Holloway, L; Kiro, Cynthia; Moore, A; Page-Curruth, A; Pearce, N; Sullivan, L; Stewart, L; Talemaitoga, A; Tepania-Palmer, G (2004)

    Report
    The University of Auckland Library

    Advice to the Minister of Health on the issues and latest evidence concerning prostate cancer screening. The National Health Committee (NHC) first reviewed the possibility of population screening for prostate cancer using the Prostate Specific Antigen or PSA test, in 1996. At that time, it recommended against population screening. Due to high public interest in prostate cancer screening and increasing use of the test, the NHC reviewed its earlier advice and published its findings in 2004. The NHC undertook its second review because it felt health care practitioners, men and the wider public needed up-to-date information based on the best available evidence to help them make decisions. It used the screening assessment criteria it had developed in 2003 (Screening to Improve Health in New Zealand) to assess prostate cancer screening in New Zealand. Consultation with organisations and individuals with an interest in prostate screening was undertaken to inform the report – see Summary of submissions in response to National Health Committee consultation paper on prostate cancer screening in New Zealand, January 2004. The NHC’s 2004 report notes there continues to be no conclusive evidence that undergoing the PSA test or digital rectal examination (DRE) for prostate cancer reduces mortality or morbidity associated with prostate cancer. The report further notes the PSA test is not completely reliable and can miss some cancers or alternatively, may set in train a cascade of interventions offering little benefit and potentially, significant harm. But, the NHC believes, concern over potential harms of screening is not sufficient reason to deny a man the test if he is fully informed and requests it. Men considering the PSA test are entitled to detailed information about its limitations, the possible diagnostic and treatment choices and outcomes and the fact that PSA screening is not recommended in New Zealand. The NHC recommends the benefits and potential for harm from prostate screening should continue to be reviewed as new evidence emerges. It recommends the Ministry of Health monitor the advances in diagnosis and treatment of prostate cancer.

All other rights are reserved by the author(s). We consider simple cube-curves in the orthogonal 3D grid of cells. The union of all cells contained in such a curve (also called the tube of this curve) is a polyhedrally bounded set. The curve's length is defined to be that of the minimum-length polygonal curve (MLP) fully contained and complete in the tube of the curve. So far, only a"rubber-band algorithm" is known to compute such a curve approximately. We provide an alternative iterative algorithm for the approximative calculation of the MLP for curves contained in a special class of simple cube-curves (for which we prove the correctness of our alternative algorithm), and the obtained results coincide with those calculated by the rubber-band algorithm.

In today s pest control operations large numbers of tracking tunnels are used to estimate the number of rodents present in the target area, providing a basis for planning the required amount of poison. The marks left in the tunnels have to be interpreted by trained experts. This article introduces two methods that make a step towards automating the process of recognizing footprints of rodents and insects. Furthermore two classification methods (Principal Component Analysis, a simple Na¨?ve Bayes classifier) are studied to distinguish the four examined insect species. Here, a combination of both classifiers proved superior to using just one method.

    You are granted permission for the non-commercial reproduction, distribution, display, and performance of this technical report in any format, BUT this permission is only for a period of 45 (forty-five) days from the most recent time that you verified that this technical report is still available from the original CITR web site; http://citr.auckland.ac.nz/techreports/ under terms that include this permission. All other rights are reserved by the author(s). We consider the following problem. Given a set of points M = {p1, p2, . . . , pm} ? Rn, decide whether M is a portion of a digital hyperplane and, if so, determine its analytical formulation. In our setting p1, p2, . . . , pm may be arbitrary points (possibly, with rational and/or irrational coefficients) and the dimension n may be any arbitrary fixed integer. We provide an algorithm that solves the problem with O(mlogD) arithmetic operations, where D is a bound on the value of the digital plane coefficients. The solution is based on reducing the digital hyperplane recognition problem to an integer linear programming problem of fixed dimension within an algebraic model of computation.

All other rights are reserved by the author(s). Using tracking tunnels or tracking cards to obtain the footprints of active animals living in a specific area is useful for biosecurity research as well as environment monitoring. In the absence of human experts, a feasible computer classifier could be constructed to identify species of insects from their footprints. The essential step to develop this classifier is to obtain representative attributes on which we can perform analysis using image processing technology, geometry, etc. This paper presents procedures for an approach to build up such a classifier by discussing three different attribute heuristics.

All other rights are reserved by the author(s). In this paper we investigate the advantages of using hexagonal grids in raster and volume graphics. In 2D, we present a hexagonal graphical model based on a hexagonal grid. In 3D, we introduce two honeycomb graphical models in which the voxels are hexagonal prisms, and we show that these are the only possible models under certain reasonable conditions. In the framework of the proposed models, we design two- and three-dimensional analytical honeycomb geometry of linear objects, as well as of circles and spheres. We demonstrate certain advantages of the honeycomb models and address algorithmic and complexity issues.
