Etransactions in the Australian supply chain setting

Many sectors of the Australian economy have, in recent years, undertaken an analysis of their supply chain structures. Each sector has determined the underlying technologies to be recommended for use on the basis of past practice in that sector and, in some cases, international practice in the sector. In this article, the authors examine the current role of e-transactions within the context of Australian supply chains. Our analysis indicates that there is a bifurcation of technical choices along the demarcations of XML and EDI business solutions. For instance, while Mining and Finance have gone the XML route, Wholesale and Retail Trade, along with Transport and Storage have chosen EDI. Moreover, the Health sector appears to be leaning towards keeping both options open to its organizations. We argue that two factors will need to be considered which will be affected greatly by this parting of the ways on the technology issue. One is the concept of ‘design for supply chain’ which involves demand generation through joint development of new products and the flow of material across different supply chain entities. The second is the impact of the growth of global trade within international economic blocs. A natural conclusion is that Australian industry must support a merging of EDI and XML standards

An authorization policy management framework for dynamic medical data sharing

In this paper, we propose a novel feature reduction approach to group words hierarchically into clusters which can then be used as new features for document classification. Initially, each word constitutes a cluster. We calculate the mutual confidence between any two different words. The pair of clusters containing the two words with the highest mutual confidence are combined into a new cluster. This process of merging is iterated until all the mutual confidences between the un-processed pair of words are smaller than a predefined threshold or only one cluster exists. In this way, a hierarchy of word clusters is obtained. The user can decide the clusters, from a certain level, to be used as new features for document classification. Experimental results have shown that our method can perform better than other methods.<br /

Australian commercial-critical infrastructure management protection

Secure management of Australia\u27s commercial critical infrastructure presents ongoing challenges to owners and the government. Although managed via a high-level information sharing collaboration of government and business, critical infrastructure protection is further complicated by the lack of a lower-level scalable model exhibiting its various levels, sectors and sub-sectors. This research builds on the work of Marasea (2003) to establish a descriptive critical infrastructure model and also considers the influence and proposed modelling of critical infrastructure dependency inter-relationships.<br /

Has political instability contributed to price clustering on Fiji's stock market?

The goal of this paper is to examine evidence of stock price clustering on the South Pacific Stock Exchange, located in Fiji, and explore its determinants. We find that stock prices cluster at the decimal of 0 and 5, with almost half of prices settling on these two decimals. Upon investigating the determinants of price clustering on the South Pacific Stock Exchange we find that price level and volume of trade have a statistically significant positive effect on price clustering. We also propose and test a âpanic trading‟ hypothesis which states political instability induces price clustering. We find evidence that political instability in Fiji induces price clustering behavior.Political instability, price clustering, Fiji

Characteristics of Australian B2B imarketplaces

Existing research on B2B iMarketplaces (and intermediaries operating them) focuses primarily on viewing US iMarketplace web sites or conducting case studies. This paper extends this work by presenting survey findings of the total identifiable population of Australian B2B iMarketplace intermediaries to describe the iMarketplace characteristics and to determine if the findings provide more generalisable support for the literature.<br /

Small firm e-business adoption : a critical analysis of theory

Purpose &ndash; The paper critiques a range of theories and evaluates their ability to provide a lens for explaining the idiosyncratic nature of small firms and their e-business adoption decisions.Design/methodology/approach &ndash; This literature review firstly summarises the existing research evidence that shows that small firms are idiosyncratic when it comes to e-business adoption. It then critiques theories commonly used in the literature in this field to examine the extent to which they take this small firm idiosyncrasy into account when explaining e-business adoption decisions.Findings &ndash; The critical analysis shows that no commonly-used theory adequately explains small firm adoption of e-business because each omits important aspects of small firm idiosyncrasy. The analysis suggests that an integrated theoretical framework is needed. Preliminary ideas on this framework are provided.Originality/value &ndash; Existing research generally applies a small number of selected theories and formulates research models of adoption factors. However, there is no systematic analysis of theories in this field and no consensus about theoretical frameworks. This paper addresses this limitation of the literature by critically evaluating the commonly used theories in terms of their individual suitability as lenses for explaining small firm e-business adoption. <br /

Securing small business - the role of information technology policy

As small and medium enterprises develop their capacity to trade&nbsp; electronically, they and their trading partners stand to gain considerable benefit from the resulting transaction efficiencies and business&nbsp; relationships. However, this raises the question of how well small business manages its IT security and the threats that security lapses may pose to the wider trading network. It is in the interest of all members of an electronic trading network, as well as governments, to assist smaller companies to secure their business data. This paper considers the relationship between IT security management and IT policy implementation among small&nbsp; businesses involved in business-to-business eCommerce. It reports the results of a survey of 240 Australian small and medium businesses&nbsp; operating in a cross-industry environment. The survey found a low level of strategic integration of eCommerce along with inadequate IT security among the respondents, despite the fact that 81% were doing business online and 97% identified their business data as confidential. Businesses which implemented satisfactory levels of security technologies were more likely than others to have an information technology policy within the organisation. The paper proposes a model that outlines the development of security governance and policy implementation for small and medium businesses.<br /

The internet, E-commerce and older people: an actor-network approach to researching reasons for adoption and use

Many older people are discovering the Internet, and some are also making good use of electronic commerce and all that goes with it. Others, however, are not adopting these technologies. This paper questions why some older people adopt Internet technologies while others do not, and offers a research framework, based on actor-network theory, for investigating adoption of Internet technologies by older people. In this paper, innovation translation is used to illustrate how specific cases of adoption have occurred. Innovation translation presents a different view of innovation than the better known theory of innovation diffusion, but one that the authors argue is better suited for research in socio-technical situations like this

Encouraging small firm up-take of SCM using education: a future research agenda

The success of supply chain management (SCM) practices often depends on small firms in the supply chain adopting these practices, yet they are often reluctant to do so. The existing literature mostly explores SCM adoption barriers rather than approaches to encourage adoption. This paper argues that an educational perspective has promise, and proposes a research agenda which should guide future studies by all researchers studying small firm SCM up-take. The agenda encompasses the diversity of small firms, the major educational players, appropriate types of education approaches and the theoretical framework to underpin this research. The paper then gives an example of how this research agenda can be applied to a specific research project which will explore the impact of the Supply Chain Knowledge Centre (SCKC), a state of the art SCM education facility developed by GS1 Australia, on small firm SCM up-take.<br /
