  • 2009 Global Network Interconnectivity (GNI) Symposium 

    Middlemiss, Melanie
    Telecommunications technologies and Internet services are experiencing unprecedented growth. Technological advances together with the growing scale of deployments are driving rapid change in the telecommunications arena. ...
  • Access to Financing and Firm Growth: Evidence from Ethiopia 

    Regasa, Dereje; Fielding, David; Roberts, Helen
    Using Ethiopian firm-level data, we model the effect of different types of financing on firm growth. The form of financing is potentially endogenous to firm growth, and one contribution of this paper is to introduce a new ...
  • An adaptive distributed workflow system framework 

    Purvis, Martin; Lemalu, Selena; Purvis, Maryam A.
    Workflow management systems are increasingly used to assist the automation of business processes that involve the exchange of documents, information, or task execution results. Recent developments in distributed information ...
  • Adaptive, evolving, hybrid connectionist systems for image pattern recognition 

    Kasabov, Nikola; Israel, Steven; Woodford, Brendon J
    The chapter presents a new methodology for building adaptive, incremental learning systems for image pattern classification. The systems are based on dynamically evolving fuzzy neural networks that are neural architectures ...
  • The African Credit Trap 

    Andrianova, Svetlana; Baltagi, Badi H.; Demetriades, Panicos O.; Fielding, David
    We put forward a plausible explanation of African financial underdevelopment in the form of a bad credit market equilibrium. Utilising an appropriately modified IO model of banking, we show that the root of the problem ...
  • Agent based web service composition in the context of a supply-chain based workflow 

    Savarimuthu, Bastin Tony Roy; Purvis, Martin; Purvis, Maryam A.
    With the advent of Web Services, more and more business organizations make their services available on the Internet through Web Services and also use other services that are available on the corporate Intranet. From the ...
  • Agent modelling with Petri nets 

    Purvis, Martin; Cranefield, Stephen
    The use of intelligent software agents is a modelling paradigm that is gaining increasing attention in the applications of distributed systems. This paper identifies essential characteristics of agents and shows how they ...
  • An agent-based architecture for software tool coordination 

    Cranefield, Stephen; Purvis, Martin
    This paper presents a practical multi-agent architecture for assisting users to coordinate the use of both special and general purpose software tools for performing tasks in a given problem domain. The architecture is open ...
  • Agent-based container terminal optimisation 

    Winikoff, Michael; Wagner, Hanno-Felix; Young, Thomas; Cranefield, Stephen; Jarquin, Roger; Li, Guannan; Martin, Brent; Unland, Rainer
    Container terminals play a critical role in international shipping and are under pressure to cope with increasing container traffic. The problem of managing container terminals effectively has a number of characteristics ...
  • Agent-based integration of web services with workflow management systems 

    Savarimuthu, Bastin Tony Roy; Purvis, Martin; Cranefield, Stephen; Purvis, Maryam A.
    Rapid changes in the business environment call for more flexible and adaptive workflow systems. Researchers have proposed that Workflow Management Systems (WfMSs) comprising multiple agents can provide these capabilities. ...
  • An Agent-based Model of Interdisciplinary Science and the Evolution of Scientific Research Networks 

    Farhat, Dan
    This study proposes an agent-based model of the impact of research success on the structure of scientific communities. In the model, heterogeneous scientists scattered about a ‘social landscape’ influence each other through ...
  • Aid and Dutch Disease in Sub-Saharan Africa 

    Fielding, David; Gibson, Fred
    International aid has an ambiguous effect on the macro-economy of the recipient country. To the extent that aid raises consumer expenditure, there will be some real exchange rate appreciation and a shift of resources away ...
  • Aid and Dutch Disease in the South Pacific 

    Fielding, David
    The impact of aid inflows on relative prices and output is ambiguous. Aid inflows that increase domestic expenditure are likely to cause real exchange rate appreciation, ceteris paribus. However, if this expenditure raises ...
  • Alcohol Expenditure, Generosity and Empathy 

    Fielding, David; Knowles, Stephen; Robertson, Kirsten
    Existing studies suggest that alcohol dependency (or recovery from alcohol dependency) is associated with lower levels of empathy and generosity. We present results from a charitable donation experiment which shows that ...
  • Alternatives to regression models for estimating software projects 

    MacDonell, Stephen; Gray, Andrew
    The use of ‘standard’ regression analysis to derive predictive equations for software development has recently been complemented by increasing numbers of analyses using less common methods, such as neural networks, fuzzy ...
  • Analysis of the macroeconomic development of European and Asia-Pacific countries with the use of connectionist models 

    Kasabov, Nikola; Akpinar, H; Rizzi, L; Deng, Jeremiah D.
    The paper applies novel techniques for on-line, adaptive learning of macroeconomic data and a consecutive analysis and prediction. The evolving connectionist system paradigm (ECOS) is used in its two versions—unsupervised ...
  • Analysis of the New Zealand and Māori on-line translator 

    Laws, Mark R; Kilgour, Richard; Watts, Michael
    The English and Māori word translator ngā aho whakamāori-ā-tuhi was designed to provide single head-word translations to on-line web users. There are over 13,000 words all based on traditional text sources, derived because ...
  • Another tale of two-sided markets 

    Kind, Hans Jarle; Stähler, Frank
    This note generalizes the frequently used Hotelling model for two-sided markets. We demonstrate an invariance theorem: advertisement levels neither depend on the media price nor on the location of the media firm. An increase ...
  • ANZUS free trade agreements: results from a global model 

    Winchester, Niven; Richardson, Martin
    When President George W. Bush received ‘fast-track’ trade promotion authority (TPA) in 2002 which, in essence, gives him much greater power to pursue trade negotiations, many economists looked with interest to see where ...
  • An application of Bayesian network for predicting object-oriented software maintainability 

    van Koten, Chikako; Gray, Andrew
    As the number of object-oriented software systems increases, it becomes more important for organizations to maintain those systems effectively. However, currently only a small number of maintainability prediction models ...
