  • Exhaled nitric oxide and the clinical control of airway inflammation

    Jones, Stuart L. (2003)

    Doctoral thesis
    University of Otago

    Measurements of exhaled nitric oxide (eNO) are non-invasive and easily measured. Levels have been postulated as providing an indication of underlying airway inflammation. This series of studies was conducted to investigate the role of eNO in measuring airway inflammation in patients with asthma and COPD (chronic obstructive pulmonary disease). 78 asthma patients controlled on maintenance inhaled corticosteroid were assessed for 2-4 weeks. Measurements of eNO demonstrated good repeatability both within-sitting (coefficient of variation (c.v.) 4.1 %) and between weekly visits (c.v. 10.5%; 95% reference range of -38 to +61% of individual patient means). Patients then underwent cessation of inhaled corticosteroid therapy until loss of control occurred or for a maximum of six weeks. Comparisons were made between eNO, symptoms, lung function, sputum eosinophils and airway hyperresponsiveness to hypertonic saline (4.5%) in predicting and diagnosing loss of control. Sixty patients (77.9%) developed loss of control. Exhaled NO increased to a greater degree in patients who developed loss of control (2.16 versus 1.44-fold increase, p=0.004). Both single measurements and changes in eNO (10ppb, 15ppb or an increase of >60% over baseline) had positive predictive values that ranged from 80-90% for predicting and diagnosing loss of control. This compared well with other more invasive markers. In a further extension of this design but with a total of 87 patients participating, 65 developed loss of control and were entered into a randomised placebo-controlled, double-blind dose-response study of 50, 100, 200 and 500μg of beclomethasone/day for eight weeks. Linear dose-response relationships between dose and changes in eNO and FEV 1 existed at one-week (p=0.002 and p=0.043 respectively) and at the end of treatment (p=0.015 and p=0.006 respectively). A similar linear dose-response relationship was seen with sputum eosinophils (p=0.037) but not with airway hyperresponsiveness. In differentiating between treatment groups eNO was superior to both FEV 1 and eosinophils. Throughout all of these study phases eNO was shown to correlate significantly with other markers of asthma control. This correlation was particularly strong with sputum eosinophils, where significant correlations were seen whether assessed as point-in-time measurements (range of r=0.46 to 0.62, p<0.001) and improving asthma control (r=0.40, p=0.002). Finally, the effect of a course of oral prednisone on eNO, lung function and 6-minute walk in 30 COPD patients was assessed. A significant decrease in eNO (-3.31ppb; 95%C.I.: -1.45 to -5.16) was seen in association with an improvement in 6-minute walk (34.36m; 95%C.I.: 22.64 to 46. 08). An eNO of ≤10ppb at baseline was associated with a negative predictive value of 82.2% in predicting a significant improvement in 6-minute walk, but the positive predictive value was only 43.7%. No improvement was seen in lung function. These results indicate that eNO measurements are reliable and provide important clinical information in the control of asthma, correlating to the degree of sputum eosinophilia. Levels can be used to predict and diagnose poor asthma control as well as demonstrating a dose-response to inhaled corticosteroid therapy. However its usefulness is limited in assessing steroid responsiveness in COPD, perhaps a reflection of the different inflammatory processes occurring. Further longitudinal studies are required to investigate whether adding serial eNO measurements into treatment algorithms leads to improved clinical outcome in both asthma and COPD.

  • A cost-benefit analysis for using the internet in the language classroom

    Reinders, Hayo (2003)

    Journal article
    Unitec

    In recent years, the Internet has obtained its place in the educational environment. As part of the examination requirements, students have to be able to use the Internet to find information and to gain experience with international communication, for example by using email. Investments in both time and money for this purpose are large, while the results are often hard to measure. Sometimes, computer literacy seems to be the only result of using computers in the classroom, the development of which may be a laudable goal, but is certainly not the responsibility of a language teacher. Using the Internet for language teaching purposes can of course provide benefits, but whether they balance the investments remains to be seen. To aid in this process the author developed a short quizz consisting of a number of questions, the answers to which determine whether the necessary investment to using a particular site is worth it. A ‘scorecard’ makes this easy.

  • RelaxNG with XML data structures

    Kennedy, D. (2003)

    Conference item
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    XML mark-up is used in a wide range of applications and in particular for data transfer via the Internet. XML textbooks and web-based tutorials typically introduce XML mark-up by the use of examples and the rules for well-formed XML, e.g. XML Tutorial. According to this popular presentation at W3schools.com the development of a DTD or schema is done after a document instance has been marked up. An XML document is a data structure. This paper proposes a methodology for XML mark-up that begins with data analysis by using a type of structure diagram (an elm tree diagram) then describes the data structure and content using Relax NC (an easier to use alternative to DTD or XML Schema) and finally does the mark-up of document instances. The instruction effectiveness and the efficiency of the different approaches are compared for two occurrences of a 3rd year degree paper.

  • NACCQ qualifications - a preformance review and future developments

    Roberton, G.; Ross, J. (2003)

    Conference item
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    In 1986 a committee, consisting of industry and polytechnic computing representatives, was formed to design a new qualification in computing that would replace the outdated New Zealand Certificate in Data Processing (NZCDP). As a result the Certificate in Business Computing (CBC) programme, a radical new approach to computing education incorporating competencybased assessment, was offered nationally in polytechnics for the first time in 1988. The National Advisory Committee on Computing Qualifications (NACCQ), formed to replace the NZCDP review committee, continued with the development of the Advanced Certificate in Business Computing (ACBC), introduced in 1989, and the National Diploma in Business Computing (NDBC), introduced the following year. The organisation has continued to strive to serve its member institutions over the last fifteen years by endeavouring to keep up with, and ahead of, developments in the rapidly changing field of Information and Communications Technology (ICT). This paper presents the findings from a comprehensive survey of NACCQ sector affiliates (includes Polytechnics and Universities) on which NACCQ qualifications and modules are currently being offered. It focuses on the question of whether the organisation is currently perceived to be addressing the needs of its members, and those of the ICT industry, in terms of the content of the current edition of the New Zealand Qualifications in Information and Communications Technology (the Blue Book).

  • The development of a graduate diploma in eCommerce

    Nesbit, T. (2003)

    Conference paper
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    In 2000 Christchurch Polytechnic Institute of Technology (CPIT) developed a new Graduate Diploma in eCommerce, which has been offered since early 2001. The purpose of this paper is to describe how the curriculum and delivery of the Graduate Diploma in eCommerce prepares its graduates for the “Inter-related Role of the eCommerce Professional” as described by Chan and Swatman (2000) and the multi-disciplinary nature of eCommerce as described by Turban et al (2002). Many tertiary education institutions in the Asia Pacific region have incorporated eCommerce and eBusiness related subjects into their curriculum, with some having created majors or specialisations for existing qualifications, while others have created new qualifications at undergraduate, graduate or post graduate level. The nature and level of many of these new qualifications have been well document by a number of writers including Chan and Swatman (2000b, 2001 and 2002). Chan and Swatman (2000a) in an analysis of the eCommerce/eBusiness job markets developed a model of the “Inter-related Role of the eCommerce Professional”. This model is in affect a three-legged stool made up of Commerce/Business, Electronics and People. A number of other writers also point to eCommerce being multidisciplinary as opposed to being a single discipline in itself, with most writers, including Turban et al. (2002), and Nesbit (2001 and 2002) reaching the point of saying that the underlying disciplines fall into the three categories of business, technology and social sciences. The paper also includes a description of how the qualification is structured into two optional specialisations of Web Programming and eBusiness Strategies and looks at the combination of courses that typical students might complete as part of the qualification.

  • The Capstone Project - a foundation for work?

    Wieck, M. (2003)

    Conference item
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    This paper represents an attempt to gauge the effectiveness of the student work placement that forms a compulsory part of the Bachelor of Information and Communication Technologies (BICT) taught at Christchurch Polytechnic Institution of Technology (CPIT). In this paper, the effectiveness will be judged in terms of how well it appears to prepare students for work within the IT industry. A survey is used given to students to establish how well they felt prepared for the workplace before and after the project and hence how they feel the placement contributes to their preparedness. Two areas are examined; specific, technical preparedness and more general competencies such as time-management, interpersonal or social skills. The study is not exhaustive, but responses are believed to reasonably represent a majority of BICT students both past and present. Further study along this path will incorporate more detailed analysis of how the employers and academic supervisors feel the project affected the student’s knowledge and skill formation.

  • Teaching computing and provision of IT support: a bridge too far?

    Wieck, M.; McPhee, J. (2003)

    Conference item
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    This paper evaluated existing models of IT support for providers of ICT tertiary education and training and other organisations. It looked at the support afforded by IT infrastructure in meeting the needs of teaching staff and their ability to deliver courses of instruction. By contrast, different models of support were examined from industry in terms of their applicability to the particular needs of the tertiary education sector. The findings so far have identified a useful basis for comparison of IT infrastructure effectiveness and highlighted likely areas of difficulty. It concludes with a discussion of alternative models of provision of IT services ending with recommendations for a more appropriate model that better reflects the particular needs of the academic environment.

  • Alcohol and drug treatment for women: clinicians' beliefs and practice

    Cowan, L.; Deering, D.; Crowe, M.; Sellman, D.; Futtermore-Colllier, A.; Adamson, S. (2003)

    Journal article
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    Clinicians’ attitudes and beliefs are an important component of service provision for women. This paper reports on the results of a New Zealand survey of alcohol and drug treatment clinicians’. Nurses were the second largest group of clinicians surveyed. The majority of clinicians did believe that women have different treatment needs to men, reflecting current literature. Differences were found in clinicians’ practice in relation to gender, work setting and caseload gender mix. These findings identify the need to more specifically investigate the actual treatment provided to women by clinicians and the views of women clients about their treatment experiences.

  • The impact of effective IT systems management on end-user productivity: an end-user perspective

    McCarthy, C.; Nesbit, T. (2003)

    Conference item
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    This paper examines the use of technology partnership agreements (TPAs) and service level agreements (SLAs) for the provision of IT services by internal IT departments, from the perspective of a group of academics involved in the teaching of information and communication technology (ICT) in the Institute of Technology and Polytechnic (ITP) sector in New Zealand. Also examined in the paper are the use of cost centres and profit centres for measuring the financial performance of internal IT departments. This paper is part of ongoing research into the management of the provision of IT services by internal IT departments, with future research likely to include the perspectives of a wide grouping of those in IT management roles in the public sector; a group of people in IT management roles in the ITP and wider tertiary education sector; those teaching in non-ICT subject areas in the ITP sector and a cross section of practitioners in the IT Industry.

  • Multi-level voltage and current reinjection ac-dc conversion.

    Liu, Yonghe (2003)

    Doctoral thesis
    University of Canterbury Library

    This thesis describes a new concept of multi-level reinjection ac-dc conversion, its main purpose being a further reduction of the harmonic content, a solution of dynamic voltage balancing for direct series connected switching devices and an improvement of high power converter efficiency and reliability. It is a combination of the multi-level, soft switching and reinjection concepts. A variety of configurations are proposed, based on the new concept, to achieve efficient voltage and current conversion. For each configuration the firing sequences, waveform analysis, steady and dynamic performances and close-loop control strategies are presented, and particular applications suggested. The ideal reinjection waveforms are first derived for perfect harmonic cancellation and then fully symmetrical approximations are made for more practical implementations. This is followed by a description and comparison of the generation circuits required for the implementation of the multi-level symmetrical reinjection waveforms. A three-level voltage reinjection scheme, implemented by adding a reinjection bridge and a reinj ection transformer to the standard twelve-pulse converter, is discussed in great detail, both for the series and parallel connections. This is followed by an investigation into the possible application of these converters to Back to Back VSC HV de interconnection; the analysis is validated by EMTDC simulations. A multi-level voltage reinjection VSC is also proposed, which uses a controllable de voltage divider to distribute the de source voltage to the two main bridges and produces high quality output waveforms. The voltage and current waveforms, the firing sequences and the capacitor voltage balancing are analyzed and verified by EMTDC simulations. In particular, the proposed VSC is shown to be an ideal solution for the STATCOM application. The multi-level reinjection CSC alternative is also described and shown to exhibit an excellent performance in the STATCOM application.
