The Role Of An Online Community To Support Overweight Adolescents: A Survey Of Australian Healthcare Professionals. Research In Progress, Leisa Armstrong, Rachel Mahncke Feb 2012

The Role Of An Online Community To Support Overweight Adolescents: A Survey Of Australian Healthcare Professionals. Research In Progress, Leisa Armstrong, Rachel Mahncke

Leisa Armstrong

In Australia, as in other developed countries, there is au increasing trend of obesity in children and adolescents. Research studies indicate that technology may be a contributing factor to this epidemic and that behavioural change may be a significant solution. One route of inquiry identified as potentially beneficial is that of the development of online communities for children and adolescents to discuss issues such as obesity to contribute to behavioural change. This research outlined in this paper aims to determine if such an online community is feasible and potentially effective to contribute to the changes required. A survey of health …

Applying Data Mining Techniques In The Selection Of Plant Traits, Dean Diepeveen, Leisa Armstrong Feb 2012

Applying Data Mining Techniques In The Selection Of Plant Traits, Dean Diepeveen, Leisa Armstrong

Leisa Armstrong

In the agricultural sector, farmers are provided with crop related information by various research agencies in order to make critical decisions about which is the most profitable crop variety choice. Research agencies provide information which is generic, rather than being tailored to the individual farmers cropping situation. A number of specific plant and growth traits are used to establish the most suitable crop varieties. When selecting crop varieties for release to growers, the application of data mining techniques to crop research data enables the customization of information to each individual farmers farming situation. The challenge for agricultural research perspective is …

C-Commerce Innovation: Unravelling The Effects Of Knowledge Ties On Embedded Network Structure, Mark Brogan, Leisa Armstrong Feb 2012

C-Commerce Innovation: Unravelling The Effects Of Knowledge Ties On Embedded Network Structure, Mark Brogan, Leisa Armstrong

Leisa Armstrong

Relative to other nations, economically significant activity in Australia and New Zealand is skewed toward micro and small business. Issues of scale and- access to resources and expertise, suggest issues for Australian and New Zealand SMEs seeking to compete in the era of the global Internet economy. Collaborative, or so-called C-commerce, has arisen as a concept and key enabler for clustering of SMEs to secure resource advantage and to promote global competitiveness. Through the lens of a C-commerce case study in tourism, this paper explores network/actors that impinge upon C-commerce innovation in an SME setting. The paper demonstrates the usefulness …

An Evaluation Of Methodologies For Eagriculture In An Australian Context, Leisa Armstrong, Dean Diepeveen Feb 2012

An Evaluation Of Methodologies For Eagriculture In An Australian Context, Leisa Armstrong, Dean Diepeveen

Leisa Armstrong

Australian agricultural producers’ profits are dependent on the decisions they make about farm productivity systems. They may use recommendations and information provided by government agencies and private consultants. For cereal growers, success is dependent on decisions made about selection of crop varieties suitable for their agronomic and climatic conditions. This paper reports on research which aimed to evaluate some current eAgriculture methodologies for their application in the Western Australian agricultural industry. In particular the paper illustrates the findings from a project which aimed to explain the variability seen in crop varieties grown in Western Australia. The problems associated with crop …

Securing J2me Mobile Application Api Using Xacml, Gautham Kasinath, Leisa Armstrong Feb 2012

Securing J2me Mobile Application Api Using Xacml, Gautham Kasinath, Leisa Armstrong

Leisa Armstrong

Following Moore's law, the numbers of mobile phones and their capabifities have increased exponentially in recent years. The platform of choice for running applications on resource constrained devices such as mobile phones, today, is the Java 2 Micro Edition (J2ME) with Connected Limited Device Configuration (CLDC). This popularity exposes the security risks. These risks include the loss of data, money and privacy. Means of securing mobile phones and communication have been weI! researched and models have been proposed, based on their success on desktop computers. However, little has been done to explore and correct inherent flaws and possible vulnerabilities in …

Selecting Areas For Land Use Change In A Catchment, Neil Dunstan, Leisa Armstrong, Dean A. Diepeveen Feb 2012

Selecting Areas For Land Use Change In A Catchment, Neil Dunstan, Leisa Armstrong, Dean A. Diepeveen

Leisa Armstrong

Some farming areas in Australia have been degraded by agricultural practices that result in rises in the water table that bring salt to the surface and reduce the quality of runoff water and the yield from pasture and crops. There is a need for a balanced choice of land uses that can reduce the salinity problem. A framework is proposed that uses catchment data and a hydrology model to predict areas with high rates of recharge and to identify sites for land use change.

An Eagriculture-Based Decision Support Framework For Information Dissemination, Leisa Armstrong, Dean Diepeveen, Khumphicha Tantisantisom Feb 2012

An Eagriculture-Based Decision Support Framework For Information Dissemination, Leisa Armstrong, Dean Diepeveen, Khumphicha Tantisantisom

Leisa Armstrong

The ability of farmers to acquire knowledge to make decisions is limited by the information quality and applicability. Inconsistencies information delivery and standards/or the integration o/information also limit decision making processes. This research uses a similar approach to the Knowledge Discovery in Databases (KDD) methodology to develop an ICT based framework which can be used to facilitate the acquisition of knowledge for farmer's' decision making processes. This is one of the leading areas of research and development for information technology in an agricultural industry, which is yet to utilize such technologies fully. The Farmer Knowledge and Decision Support Framework (FKDSF) …

An Information-Based Decision Support Framework For Eagriculture, Leisa Armstrong, Dean Diepeveen Feb 2012

An Information-Based Decision Support Framework For Eagriculture, Leisa Armstrong, Dean Diepeveen

Leisa Armstrong

The ability of farmers to acquire knowledge to make decisions is limited by the information quality and applicability. An inconsistency in information delivery and standards for the integration of information also limits the decision making process. Knowledge Discovery in Databases (KDD) methodology described for the data mining is an example of how frameworks can be used to facilitate such data integration. This research will examine how such a ICT based framework can be used to facilitate the acquisition of knowledge for the farmer decision making process. The Farmer Knowledge and Decision Support Framework (FKDSF) takes information provided to farmers and …
