  • A software framework for application development using ZigBee protocol

    Savarimuthu, Bastin Tony Roy; Bruce, Morgan; Purvis, Maryam A. (2009-04)

    Working or discussion paper
    University of Otago

    The problem with the uptake of new technologies such as ZigBee is the lack of development environments that help in faster application software development. This paper describes a software framework for application development using ZigBee wireless protocol. The architecture is based on defining XML based design interfaces that represent the profiles of ZigBee nodes that are used in the application.

  • Software development, CASE tools and 4GLs—A survey of New Zealand usage. Part 1: 750 New Zealand organisations

    MacDonell, Stephen (1993-11)

    Working or discussion paper
    University of Otago

    This paper reports the results of a recent national survey which considered the use of CASE tools and 4GLs in commercial software development. Responses from just over 750 organisations show a high degree of product penetration, along with extensive use of package solutions. Use of 3GLs in general, and of COBOL in particular, is still relatively widespread, however. In terms of systems analysis and design techniques under a CASE/4GL environment, screen and report definition is the most preferred technique, although both dataflow analysis and data modelling also feature strongly.

  • Economic integration and the choice of commodity tax base with endogenous market structures

    McCracken, Scott; Stähler, Frank (2007-02)

    Working or discussion paper
    University of Otago

    This paper analyzes the choice of commodity tax base when countries set their taxes non-cooperatively in a two-country symmetric reciprocal dumping model of intra-industry trade with free entry and trade costs. We show that the consumption base (destination principle) dominates the production base (origin principle) when trade costs are high or demand is linear. For lower levels of trade costs and nonlinear demand, the welfare ranking of the two tax bases is ambiguous. Hence, there is no clear preference for a tax principle with an ongoing movement towards closer economic Integration. JEL-Classification: F12, H20.

  • Finding medical information on the Internet: Who should do it and what should they know

    Parry, David (1999-06)

    Working or discussion paper
    University of Otago

    More and more medical information is appearing on the Internet, but it is not easy to get at the nuggets amongst all the spoil. Bruce McKenzie's editorial in the December 1997 edition of SIM Quarterly dealt very well with the problems of quality, but I would suggest that the problem of accessibility is as much of a challenge. As ever-greater quantities of high quality medical information are published electronically, the need to be able to find it becomes imperative. There are a number of tools to find what you want on the Internet---search engines, agents, indexing and classification schemes and hyperlinks, but their use requires care, skill and experience.

  • Classroom tariff wars: a tariff setting game

    Winchester, Niven (2004-01)

    Working or discussion paper
    University of Otago

    This paper outlines a classroom tariff setting game that allows students to explore the consequences of import tariffs imposed by large countries (countries able to influence world prices). Groups of students represent countries, which are organised into trading pairs. Each group’s objective is to maximise welfare by choosing an appropriate ad valorem tariff. The game is built on a computable general equilibrium model, which allows each nation’s utility and terms of trade under alternative tariff regimes to be expressed quantitatively. The exercise encourages students to consider terms of trade improvements and efficiency losses resulting from large-country tariffs and provides a backdrop to discuss the Nash equilibrium of a tariff war. Feedback from students who have participated in trial simulations indicates that the game is a useful supplement to traditional teaching methods.

  • Establishing relationships between specification size and software process effort in CASE environments

    MacDonell, Stephen (1995-07)

    Working or discussion paper
    University of Otago

    Advances in software process technology have rendered many existing methods of size assessment and effort estimation inapplicable. The use of automation in the software process, however, provides an opportunity for the development of more appropriate software size-based effort estimation models. A specification-based size assessment method has therefore been developed and tested in relation to process effort on a preliminary set of systems. The results of the analysis confirm the assertion that, within the automated environment class, specification size indicators (that may be automatically and objectively derived) are strongly related to process effort requirements.

  • An innovative approach to National Football League standings using optimal bonus points

    Winchester, Niven; Stefani, Raymond T. (2009-06-01)

    Working or discussion paper
    University of Otago

    Bonus points provide a simple way to improve the accuracy of league standings. We investigate the inclusion of bonuses in the National Football League (NFL) using a prediction model built on league points. Both touchdown-based and narrow-loss bonuses are shown to be significant. Our preferred system awards four points for a win, two for a tie, one point for scoring four or more touchdowns and one point for losing by seven or fewer points. Such a system would also make it easier for supporters to identify playoff contenders and place importance on otherwise meaningless end-of-game plays.

  • Exploiting the advantages of object-oriented programming in the implementation of a database design environment

    Stanger, Nigel; Pascoe, Richard (1997-06)

    Working or discussion paper
    University of Otago

    In this paper, we describe the implementation of a database design environment (Swift) that incorporates several novel features: Swift’s data modelling approach is derived from viewpoint-oriented methods; Swift is implemented in Java, which allows us to easily construct a client/server based environment; the repository is implemented using PostgreSQL, which allows us to store the actual application code in the database; and the combination of Java and PostgreSQL reduces the impedance mismatch between the application and the repository.

  • Open market share repurchases in New Zealand

    Henderson, George (2000)

    Masters thesis
    University of Otago

    When a firm repurchases its own common stock, it buys back a proportion of its own equity from existing shareholders. For open market transactions the stock is acquired at market value and in an efficient market the transfer should not change shareholders' wealth. However, empirically, such corporate activity in American markets is generally associated with stock price increases and, consequently, increases in remaining shareholder wealth. The purpose of this study is to examine the effect of open market share repurchases on the share price of New Zealand firms. If any abnormal returns are identified then the hypotheses suggested by American studies will be investigated to see which, if any, hold for the New Zealand case.

  • A comparison of IPOs from small and medium sized enterprises: China vs Australia

    Ze, Tian (2000)

    Masters thesis
    University of Otago

    The general market behaviour of unseasoned new issues of Chinese A-shares and Australian common stock at the time of first day trading on respective stock exchanges is investigated, presenting a time-series analysis of the monthly volume and average initial returns on initial public offerings over a certain period of time. Also, the correlation of volume and underpricing among different groups of companies according to their size is studied. The underpricing of new stock issue defined as initial returns is widespread. The scale is extreme, especially on both the Shanghai Securities Exchange (SHSE) and Shenzhen Stock Exchange (SZSE) of China. The percentage of IPOs for small and medium sized enterprises is increasing in China and decreasing in Australia on average during the period presented in this paper. The results show that there is no significant difference in size between the companies listed on SHSE and SZSE in terms of total asset or revenue.
