    VLBI is the only space-geodetic technique which gives direct access to the Earth's phase of rotation, i.e. universal time UT1. Beside multi-baseline sessions, regular single baseline VLBI experiments are scheduled in order to provide estimates of UT1 for the international space community. Although the turn-around time of such sessions is usually much shorter and results are available within one day after the data were recorded, lower latency of UT1 results is still requested. Based on the experience gained over the last two years, an automated analysis procedure was established. The main goal was to realize fully unattended operation and robust estimation of UT1. Our new analysis software, named c5++, is capable of interfacing directly with the correlator output, carries out all processing stages without human interaction and provides the results for the scientific community or dedicated space applications. Moreover, the concept of ultra-rapid VLBI sessions can be extended to include further well-distributed stations, in order to obtain the polar motion parameters with the same latency and provide an up-to-date complete set of Earth orientation parameters for navigation of space and satellite missions.

    We carried out the intercomparison experiment between VLBI and GPS to show that VLBI can measure the correct time difference. We produced an artificial delay change by stretching the Coaxial Phase Shifter which was inserted in the path of the reference signal from Hydrogen maser to the Kashima 11m antenna. Concerning the artificial changes, VLBI and the nominal value of Coaxial Phase Shifter show good agreement, i. e. less than 10ps. Thus it is concluded that the geodetic VLBI technique can measure the time differences correctly.

  • Suburban interventions : understanding the values of place and belonging through collaboration

    Woodruffe, Paul; Unitec Institute of Technology. The everyday collective laboratory (2012-05-23)

    Journal article

    How can a socially defined project facilitate meaningful knowledge transfer between community, corporate and institution? In order to address this question, this paper focuses on an ongoing live project in suburban Auckland New Zealand begun in 2010, undertaken by a post-graduate student and researcher collective. The collective currently creates subtle interventions sited within local cyberspace, and through this current project will employ impermanent and small-scale design to advocate for a series of neglected and disputed sites. It explores the impact and value the presence of artists and designers working within local communities can have, and “champions the role of the artist in the development of the public realm, and their intuitive response to spaces, places, people and wildlife” (Wood 2009, p.26). The significance of this project is that it promotes a collaborative and multidisciplinary methodology that works with community groups to advocate to corporate entities for a wider social and environmental awareness of specific sites. This paper aims to explain the processes and findings of the project to date through both its successes and failures. It also proposes the possibility of the methodology being transferred to undergraduate and post-graduate study as a tool to promote multi-disciplined collaborate project briefs that focus on community well being ... One of the most important findings from the first project in Memorial Avenue was the fact that the local residents had a complete aversion to what they perceived as a “design” proposition. The notion of a designer coming into their neighbourhood with a plan to place a design into or onto the landscape without their request was unacceptable to them. So the document prepared for the heritage walkway proposal contained nothing that could be called landscape design for construction, and it was vital that no sense of urgency or externally driven timetables were introduced to the process, and that the document was seen as a gift and a celebration of their landscape, culture and heritage instead of a plan and an agenda for development.

  • Encouraging students to think strategically when learning to solve linear equations

    Robson, D. E.; Abell, W.; Boustead, T. (2012)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    Students who are preparing to study science and engineering need to understand equation solving but adult students returning to study can find this difficult. In this paper, the design of an online resource, Equations2go, for helping students learn to solve linear equations is investigated. Students learning to solve equations need to consider their overall strategy as well as the procedures for each step. Students were encouraged to develop strategies for solving equations with interactive software, Equations2go, which allowed students to decide on strategies while the computer carried out the procedures. The results of trials showed that the software helped students solve equations which they could not solve on their own. Some of the students were then able to successfully transfer their learning to solving linear equations with pen and paper.

  • Pancreatic stone and treatment using ERCP and ESWL procedures: a case study and review

    Hayes, J.; Ding, S. (2012)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    Introduction Pancreatic duct stones are found in 22 to 60% of patients with chronic pancreatitis (CP). The stones can lead to obstruction of the outflow of pancreatic secretions causing increased intraductal pressure. The pancreas is relatively noncompliant. Therefore the rise in intraductal pressure can induce tissue hypertension and ischemia. This can be a major factor causing pain in patients with CP. This hypothesis is supported by the observation that symptoms may improve following pancreatic duct drainage. Case presentation: A 62-year-old woman presented with persistent epigastric pain. Investigations revealed calcifications within the main pancreatic duct and head of the gland. Treatment with endoscopic retrograde cholangiopancreatography (ERCP) and extracorporeal shock wave lithotripsy (ESWL) achieved a good outcome. Conclusion: Standard endoscopic removal of the stones proved impossible so treatment with ESWL was undertaken. Following fragmentation, the calculi and fragments passed spontaneously or were removed endoscopically. If pancreatic stones cannot be removed endoscopically, ESWL should be considered prior to surgery.

  • Celebrity, infamy, poker

    Austrin, T.; Farnsworth, J. (2012)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    A celebrity world that receives surprisingly little attention is poker. Yet it’s one richly populated with its own celebrities and the celebration of success, both financial and reputational. Recently, there have been two new reasons to look at poker, and two questions that arise in the process. One reason was the release in March 2012 of a new documentary on poker, All-in: the poker movie, narrated by Hollywood star Matt Damon. The other was poker’s Black Friday on 15 April 2011, when US regulators closed down its biggest online-gambling sites, charging three major poker sites with bank fraud, illegal gambling and extensive money laundering.

    This study evaluated the impact of a high-intensity strength training session on rowing sprint performance. Ten male club rowers performed a baseline counter-movement jump (CMJ) and a 250 m rowing ergometer sprint (250 m). Twenty-four hours after baseline, participants performed a high-intensity strength training session (ST) consisting of multi-joint barbell exercises. At 24 h, 48 h and 72 h post-ST, CMJ and 250 m were repeated alongside assessment of plasma creatine kinase (CK) and perceived muscle soreness. At 24 h post-ST 250 m performance decreased significantly (90% CI: 0.3 – 0.7 s), but returned to pre-test values at 48 h. There was a significant decrease in CMJ height at 48 h post ST (90% CI: -0.7 – -4.1 cm). Perceived muscle soreness was significantly greater than baseline at all assessed time points following ST (p < 0.05). There was a significant increase in CK from baseline to 24 h (90% CI: 146 – 390 U/L). High-intensity strength training was observed to adversely affect 250 m rowing ergometer performance after 24 h and coincided with transient muscle damage.

  • A virtual laboratory environment for tertiary educational institutions

    Correia, E.; Watson, R.; Quintana, A.; Perera, M. (2012)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    Computer laboratories at tertiary educational institutions need to be flexible and easy to manage, as they typically cater for a wide range of needs. This article describes how a particular virtual laboratory environment can be extended to include server-based virtualization. It explores some of the major technical challenges of implementing one particular hypervisor and associated management software, specifically to deploy a set of virtual machines that form part of a particular course, as this is one of the envisaged uses for this technology. It goes on to suggest a number of solutions and includes two scripts that can serve as templates for automating the creation and removal of sets of student virtual machines.

  • A new epizoic laelapid mite from the New Zealand sand scarab Pericoptus truncatus larvae and its isotopic ecology

    Clark, J. M. (2012)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    A new genus Mumulaelaps (Mesostigmata: Laelapidae: Hypoaspidini) is proposed to hold large, pale, agile, gregarious mites associated with the larvae of the endemic xylophagous sand scarab Pericoptus. Mumulaelaps ammochostos sp. n. is described and illustrated as its type species from P. truncatus (Fabricius) from Southshore, Christchurch, New Zealand. The new genus bears a novel mix of characters shared with Hypoaspis G. Canestrini, 1884 and Coleolaelaps Berlese, 1914 but differs from both by having, in both sexes, stout terminal spines al1 and pl1 on legs II IV and bearing long or macrosetae of the dorsal series on femora and genua of legs IIIV. Both sexes have leg IV longest and leg II shortest with III never longer than I. The posterior edge of the sternal shield is deeply concave; the post anal seta is longer than the paranals; the hypostomal seta h3 clearly longer than h1 or h2. Stable isotopic (13C/12C; 15N/14N) analysis showed that the new species is not parasitic, but its trophic association with P. truncatus is unclear. It may feed on the hypopodes of Sancassania (Caloglyphus) or nematodes associated with P. truncatus.

  • The role of therapeutic alliance in treatment for people with mild to moderate alcohol dependence

    Richardson, D.F.; Adamson, S.J.; Deering, D.E.A. (2012)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    In an exploratory study of Therapeutic Alliance (TA) in brief outpatient treatment for alcohol dependence the relationship was investigated between TA and treatment outcome (measured at 6 weeks and 6 months) for 69 alcohol dependent clients participating in a randomised control trial between Motivational Enhancement Therapy and Non Directive Reflective Listening. TA was significantly higher for clients who attended all four sessions. The correlation between TA and change in per cent days abstinent (PDA) between baseline and 6 weeks approached significance. TA was significantly correlated with the Alcohol Problem Questionnaire (APQ) at 6 months and with change in APQ scores between baseline and 6 months. These relationships remained significant when treatment assignment was controlled for. Whilst there was a trend towards a relationship between TA and change in PDA between baseline and 6 months, this trend no longer remained when both treatment assignment and early change in drinking levels were controlled for. Therapeutic alliance may be a useful additional maker to predict outcome, but early treatment response appears to be a better predictor.
