    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    Objectives: The aim of this study was to examine the effects of hemolysis, rapid chilling, time, and the addition of a maleimide on the stability of human plasma ACTH measurements. Design and methods: Partially hemolyzed EDTA blood (n = 10), initially at 37 °C, was centrifuged at 4 °C either immediately or after rapid chilling in ice/water. Plasma ACTH was then measured either immediately, or after 1 h at 22 °C with or without the addition of 2 mM N-phenyl maleimide (NPM). Results: For 0.2% hemolysis compared to no hemolysis, the mean (±SEM) loss with immediate centrifugation and immediate ACTH measurement was 11 ± 1%. This loss was significantly (p < 0.002) reduced to 6 ± 1% by an initial rapid chilling of the samples. For analysis after 1 h at 22 °C, the addition of NPM decreased the loss of ACTH from 15 ± 2% to 2 ± 2% (p < 0.002). Conclusion: Rapid chilling, prompt analysis, and addition of NPM can each reduce the interference of hemolysis in the measurement of plasma ACTH concentrations.

  • Process and strategy influences on product development performance in New Zealand

    de Waal, A.; Knott, P. (2010)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    This study is the first to evaluate the outcomes of alternative new product development (NPD) strategies among New Zealand firms. For each of six distinct NPD strategies, we assess performance by selecting the most applicable of 12 measures. We find that new product strategies produce better results than product improvement strategies, although managers rated profit margins unsatisfactory for all six NPD strategies. Our sample firms seldom reported using formalised NPD process or strategy, but when they did, this correlated positively with improved performance in all 12 measures. Firms generally recognised their NPD process performance as poorer than their product performance.

  • Identification of an optimal sampling position for stable isotopic analysis of bone collagen of extinct moa (Aves: Emeidae)

    Holdaway, R.; Hawke, D.J.; Bunce, M.; Allentoft, M. E. (2011)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    Stable isotopic (δ13C; δ15N) analysis of bone collagen and other refractory biological materials is a mainstay of palaeoecological research, but comparability between individuals depends on homogeneity within the sample specimens. Long bones of extinct New Zealand moa display lines of arrested growth that reflect prolonged development over several years, leading to potential systematic inhomogeneity in stable isotopic enrichment within the bone. We tested whether the isotopic content within a Euryapteryx curtus tibiotarsus is homogeneous by measuring δ15N and δ13C values in 6 adjacent 1cm-diameter cortical bone cores arranged along the bone axis from each of the proximal and distal ends. We then measured isotopic ratios in 5 radial slices of a core from the mid-shaft of a Pachyornis elephantopus tibiotarsus to see if there was any depth (ontogenetic) effect at a single sampling point. The δ13C value increased with distance from the proximal bone end, but neither δ13C nor δ15N values in samples from the distal end of the bone were correlated with position. Within mid-shaft cortical bone, the δ13C value decreased with depth but δ15N values were constant. Sampling the entire depth of cortical bone from the caudal surface at the distal end of the tibiotarsus, if feasible, therefore provides a spatially homogenous material, free of maturation effects on stable isotopic composition. If for any reason that position cannot be sampled, the outer (radial) layer at the mid-shaft can be substituted.

  • What exposure do student nurses have to primary health care and community nursing during the New Zealand undergraduate Bachelor of Nursing programme?

    Betony, K.; Yarwood, J. (2013)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    A research project to examine the theoretical and practical exposure student nurses have to Primary Health Care (PHC) and community nursing in their undergraduate programme was undertaken in New Zealand (NZ). Providing quality clinical placements for health care students is acknowledged as a major challenge for tertiary institutions. In order to reflect the current shift in health care delivery from hospital to community settings, one such challenge is to ensure students receive appropriate theoretical programme content and clinical experience in PHC and community settings. The project consisted of a review of relevant international literature, and a questionnaire sent to all NZ tertiary institutions providing a Bachelor of Nursing (BN). Findings included a variable understanding of the concept of PHC, a lack of appropriate PHC placements across the country, competition for student placements in PHC, and professional organisation requirements for student supervision impacting on placement availability. Innovations identified to increase PHC placements comprised the establishment of Dedicated Education Units (DEUs), curriculum revision, and final year PHC placements offered only to students targeting PHC settings on registration. Study recommendations involve establishing a regional rather than a local approach to managing clinical placements, increasing professional governance support and reviewing clinical placement funding.

  • Reporting climbing grades and grouping categories for rock climbing

    Draper, N.; Canalejo, J.; Shearman, J. (2011)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    Rock climbing is an increasingly popular adventure sport with a growing research base. To date the growth of research and reporting styles has been somewhat haphazard and as a consequence comparison between studies can be problematic. The aim of this paper was to make suggestions about a number of changes that could be made to improve the consistency in reporting between studies. Included with this paper are two new tables, one each for male and female climbers. These provide comparative grading scales for use in reporting for future studies. These tables also provide a suggested framework for grouping climbers according to their ability. Using the tables researchers could group the climbers in their study by a category name (lower grade, intermediate, advanced, elite or higher elite climber) or by a number (level 1–5). In addition, the authors make recommendations about climber characteristics that could usefully be reported in future to assist comparison between studies. It would be helpful to readers if the self-reported, highest lead climbs (on-sight and redpoint) could be reported for a climbing group, along with the types of climbing regularly undertaken.

  • Nurses' role in caring for people with a comorbidity of mental illness and intellectual disability: A literature review

    Taua, C.; Hepworth, J.; Neville, C. (2011)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    This article examines literature on the role of the nurse caring for people with a dual disability (DD) of intellectual disability and mental illness. A search of the literature between 2000 and 2010 resulted in a total of 21 articles that met the inclusion criteria. Seven key categories of the role of the nurse were identified: (i) advocacy/health promotion (including working with family); (ii) assessment/case management; (iii) behavioural interventions; (iv) communication; (v) leadership and the nurse's role within the multidisciplinary team; (vi) functions regarding medication administration; and (vii) safety/risk management. There is a paucity of research about the role of nurses working with people with DD, although a number of opinion-based articles exist. This article identifies a need for the role of the nurse working in DD to be more clearly articulated and for the development of evidence to guide best practice.

  • Sport-specific power assessment for rock climbing

    Draper, N.; Dickson, T.; Blackwell, G.; Priestley, S.; Fryer, S.; Marshall, H.; Shearman, J.; Hamlin, M.; Winter, D.; Ellis, G. (2011)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    AIM: The popularity of rock climbing has resulted in a growing research base for the sport. However, at present there is a lack of sport-specific measures of performance in the field. The aim of this study was to examine the use of the powerslap test as a sport specific power measure. METHODS: The participants in this study were categorised into four different ability groups (novice, intermediate, advanced and elite) based on self reported lead grade. Two separate experiments were conducted to determine validity and reliability. The powerslap test was conducted on a revolution board with two variations – wide and narrow grip, for both sides of the body. The test started with the climber hanging at full extension from two holds from which a pull up movement was made releasing one hand to slap a scaled score board above. RESULTS:There was a significant relationship between powerslap scores and climbing ability (Left Wide: r=0.7, P<0.0005). Limits of agreement and intra-class correlation indicated that the powerslap test is a reliable performance measure. CONCLUSION:According to the present findings the narrow grip variation of the powerslap test is a useful sport-specific power test that is related to climbing performance.

  • Disaster preparedness in the tourism industry: A New Zealand case study of constraints and training response

    Garside, R.; Christianson, A.; Johnston, D.; Graham, L. (2011)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    Key factors that influence disaster preparedness of organisations at risk from natural hazards are presented in this paper to raise awareness of managers and human resource development specialists. Primary business and regulatory reasons that justify preparedness, and issues that constrain it, are considered from a global and local perspective and applied to a commercial ski area on the slopes of the active Ruapehu volcano in New Zealand. In particular, the case study examines the effectiveness of staff training as an important part of a disaster response plan. Lessons learnt from this case identify a number of points that could be generalised to enhance workplace preparedness capacity in both low and high probability disaster events caused by natural or human-induced hazards.

  • A Māori approach to management: Contrasting traditional and modern Māori management practices in Aotearoa New Zealand

    Mika, J.P.; O'Sullivan, J.G. (2014)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    This is a conceptual article located in the discourses of indigeneity, post-colonialism and critical management studies in which we seek to renew interest in Māori management as a distinctive form of management within Aotearoa New Zealand. We discuss defining Māori management and Māori organisations and their relevance for today's organsiations in New Zealand and internationally. We examine differences and similarities between Western and Māori management in terms of the four functions of management adapted from principles first proposed by Fayol in 1949. We propose a theoretical model of Māori management and discuss the implications of Māori management for management research, policy and practice.

  • Perspectives of new trades tutors: boundary crossing between vocational identities

    Chan, S. (2012)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    This article reports on a study of the perspectives of new tutors teaching traditional vocational trades who recently commenced teaching in the Institutes of Technologies and Polytechnics (ITPs) sector in New Zealand. The perspectives are collated from questionnaires and interviews of 13 tutors, from five ITPs, who have been teaching full-time for two years. In this article, a focus is made on the transformation process from expert trade worker to effective trades tutor, along with suggestions to assist the ‘boundary crossing’ process between two diverse vocational identities. Suggestions include aligning trades tutors’ existing workplace training-based conceptualisations of teaching and learning to extend trades tutors’ teaching craft knowledge, skills, and dispositions.

  • The progress to digital in New Zealand

    Norris, P. (2013)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    New Zealand began the transition to digital television relatively late compared to other developed countries. When the policy framework was established in 2006, it centred on a Freeview model, as a counter to the pay TV platform that had been digital since 1998, achieving considerable penetration in that time. This article will examine the progress of the transition from 2006 to analogue switch-off (ASO) that began in 2012 and is to be completed by the end of 2013. It will note the light-handed nature of regulation and government policy, the impact of a change of government, the ultimate failure of an attempt at a multi-channel strategy and the reduction of public broadcasting.

  • New mites Terraphagus antipodus gen. n., sp. n. and Neohyadesia minor sp. n. (Acarina: Astigmata: Algophagidae) from islands of the Southern Ocean

    Clark, J.; Andrews, N. (2012)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    Mites are a diverse and important component in the soils of the Southern Ocean islands, but for many groups, their taxonomy and biogeography is little studied. This paper reports the Algophagidae, a poorly known family, from the New Zealand region for the first time. The study used soil samples from seabird burrows, brackish algal wrack samples and a museum collection to recover specimens. Terraphagus antipodus gen. n., sp. n. is described from grey petrel Procellaria cinerea burrow soil on the Antipodes Islands, New Zealand. The axillary organ is confined to the dorsum; the epigynal apodeme ends are fused with the ends of coxal apodeme II; seta 2a and ω2 are absent, and the famulus is bilobed. Males have the sternum fused to coxal apodemes II; the tarsal setae of legs I, III and IV of the male are modified for mate guarding. The short stout legs I and II end in huge spines in females as e, d, q, s, wa and hT. From brackish algal wrack, Lake Forsyth/Wairewa, Canterbury, New Zealand, another algophagid Neohyadesia minor sp. n. is described and illustrated. The new species is the smallest known algophagid. A neohyadesid collected in 1961 is newly reported here from Eudyptes sp. penguin rookery mud from North Head, Macquarie Island. These records further extend the known microhabitats of the family to the allochthonous marine seabird nutrient flow into islands in the New Zealand region and make Neohyadesia Hughes and Goodman, 1969 present in all Southern Ocean provinces.

  • A preliminary investigation into pre-competitive mood states of advanced and novice equestrian dressage riders

    Wolframm, I.; Shearman, J.; Micklewright, D. (2010)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    Emotional composure is considered critical in equestrian sports. The aim of the study was to investigate pre-competitive mood states in dressage riders. Thirteen advanced and 13 novice British riders completed the Profile of Mood States Questionnaire (POMS) prior to competing. A multivariate analysis of variance (MANOVA) was performed to test for a main effect of mood states on competence levels, with subsequent investigation for significant differences of individual mood states using Bonferroni adjusted alpha levels. Levels of confusion were nearing significance between advanced and novice riders, suggesting greater processing efficacy and task-specific concentration for more advanced riders. Sport psychological interventions for equestrians should focus on lowering levels of confusion and increasing task-orientated focus in novice riders.

  • Psychodrama at distance: Effective supervision practice using communication technologies

    Farnsworth, J. (2011)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    Psychodrama and electronic technologies seem unlikely bedfellows. As this paper demonstrates, they are, in fact, made for each other though surprisingly little has been written about their combined potential. Drawing on vignettes and case examples as illustration, John Farnsworth demonstrates how effective supervision can take place in the absence of a physical psychodrama stage. He describes the way in which he uses all aspects of the psychodrama method via email, phone, digital and online communications, to create warm, functional working relationships. Psychodramatists are invited to reflect on the way that psychodrama can and will be used in the emerging vibrant electronic worlds of the future.

  • Skeletal muscle fat metabolism after exercise in humans: influence of fat availability

    Kimber, N.E.; Camerson-Smith, D.; McGee, S.L.; Hargreaves, M. (2013)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    The mechanisms facilitating increased skeletal muscle fat oxidation following prolonged, strenuous exercise remain poorly defined. The aim of this study was to examine the influence of plasma free fatty acid (FFA) availability on intramuscular malonyl-CoA concentration and the regulation of whole-body fat metabolism during a 6-h postexercise recovery period. Eight endurance-trained men performed three trials, consisting of 1.5 h high-intensity and exhaustive exercise, followed by infusion of saline, saline + nicotinic acid (NA; low FFA), or Intralipid and heparin [high FFA (HFA)]. Muscle biopsies were obtained at the end of exercise (0 h) and at 3 and 6 h in recovery. Ingestion of NA suppressed the postexercise plasma FFA concentration throughout recovery (P < 0.01), except at 4 h. The alteration of the availability of plasma FFA during recovery induced a significant increase in whole-body fat oxidation during the 6-h period for HFA (52.2 ± 4.8 g) relative to NA (38.4 ± 3.1 g; P < 0.05); however, this response was unrelated to changes in skeletal muscle malonyl-CoA and acetyl-CoA carboxylase (ACC)β phosphorylation, suggesting mechanisms other than phosphorylation-mediated changes in ACC activity may have a role in regulating fat metabolism in human skeletal muscle during postexercise recovery. Despite marked changes in plasma FFA availability, no significant changes in intramuscular triglyceride concentrations were detected. These data suggest that the regulation of postexercise skeletal muscle fat oxidation in humans involves factors other than the 5′AMP-activated protein kinase-ACCβ-malonyl-CoA signaling pathway, although malonyl-CoA-mediated regulation cannot be excluded completely in the acute recovery period.

  • Tenuous affair: Environmental and outdoor education in Aotearoa New Zealand

    Straker, J.; Irwin, D. (2015)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    The relationship between outdoor education and environmental education in Aotearoa New Zealand has undergone many changes since formal education began in early colonial times. Discussion draws from qualitative doctoral research undertaken by the authors that investigated education for sustainability in outdoor education and howmeaning is ascribed to outdoor experiences. The article describes how environmental education and outdoor education had common historical roots in nature studies that eventually were teased apart by the development of separate agendas for learning and assessment, coupled with the political context of the 1970s and 1980s. The article finds that contemporary forces relating to the economy, society and the environment are now driving a re-engagement of the two discourses in Aotearoa New Zealand at a variety of levels, from schools to national bodies, and that this re-engagement signals a positive outcome for addressing key environmental issues and engaging students in the outdoors.

  • Going commercial: Navigating student radio in a deregulated media marketplace

    Reilly, B.; Farnsworth, J. (2015)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    This article describes an unusual form of student instructional radio, which is organized to run as a fully commercial broadcaster. Drawing on the case of a New Zealand student station, Mode 96.1FM, we look at how it functions in a highly competitive commercial environment. The student-run station reformats itself every year and attempts to emulate the styles and success of much larger national and local commercial music stations. We investigate two aspects. First, the tensions this creates between commercial, industry and educational objectives. Second, how students become located within the commodified speech practices intrinsic to marketing and branding. We also discuss how the station attempts to reconcile these in terms of seeking out diverse listening publics.

  • Soil selenium in a forested seabird colony: distribution, sources, uptake by plants, and comparison with non-seabird sites

    Hawke, D. J.; Wu, J-R. (2012)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    Seabirds vector selenium (Se) into terrestrial ecosystems in Antarctica and on tropical coral islands, but factors controlling distribution within affected soils are unknown, especially in temperate regions. At a Westland petrel (Procellaria westlandica) breeding colony on mainland New Zealand, the concentration of Se in petrel guano (3.6 mg kg–1) exceeded soil parent material (0.8 mg kg–1) and in all but two soil samples (range 1.2–4.2 mg kg–1; n = 52). External Se (Se not derived from parent material) accounted for 649% (means.d.) of soil Se. Measurements were also made at a former seabird breeding site, and at a site with no Holocene seabird breeding. Median surface-soil Se concentrations (mg kg–1) were in the order burrow soil (2.6) > adjacent forest floor (2.2) > former breeding site (1.0) > control site (0.2), with significant differences between burrow soil and (1) the former breeding site and (2) the control site. In a linear regression model, soil pH, and d15N were the only significant predictors of external Se in colony soil. The correlations are consistent with seabird input driving both the Se supply and increased sorptive uptake in an environment acidified by seabird guano. Despite the enhanced Se in colony soil, median foliage concentrations (tree fern 0.05 mg kg–1, nikau 0.08 mg kg–1) were close to the accepted minimum for herbivore nutrition. Seabirds therefore contribute significant Se to breeding colony soils in temperate areas, but this is not necessarily transferred to plant foliage.

  • Digital children's channels: A comparative analysis of three locally launched channels

    Zanker, R.; Lustyik, K. (2013)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    There are over two billion children worldwide under the age of 18, who are targeted by an increasing number of television channels solely dedicated to them. As such globally circulated programmes and networks expand their reach using digital platforms, is there a need – and room for – locally produced television content for young people? From the perspective of national media policy advocates, locally developed, produced and broadcast programmes can provide children with a sense of their own place in an increasingly complex globalized media landscape and ensure that programmes are developed with the interest, perspective and views of local children in mind. This article explores the dichotomy between ‘local’ and ‘global’ television content targeting children in the context of debates on media globalization. Our three case studies from radically different media policy environments, focus specifically on locally produced content offered on dedicated national children‘s digital television channels launched locally to promote the cultural heritage of a specific nation or region. They provide concrete examples of how local content is conceptualized and what types of content children have to choose from. Our findings are paradoxical. Although each channel has been created to speak back to dominant audio-visual children’s flows from the periphery, our findings are that the better funded nationally based dedicated children’s channels have grown into successful market players beyond original national boundaries. The first case study examines dedicated local children’s provision in New Zealand, focusing on TVNZ6, a digital children‘s channel that operated as part of the public service broadcasting sector. The second case study focuses on children‘s television content in Hungary and uses the case of Minimax network Hungary, an Eastern European regional commercial targeting children growing up in a dynamically transforming post-communist media system. The third case study looks at television content produced in the Middle East by focusing on Al Jazeera Children’s Channel (JCC), a pan-Arabic non-commercial edutainment channel established in Qatar and funded by the Qatar Foundation.
