The role and contribution of private land in Victoria to biodiversity conservation and the protected area system

The distribution and attributes of properties involved in three major programs for biodiversity protection on private land in Victoria, Australia, was investigated to determine their role in relation to the reserve system. Overlaying of dowsets in a geographic information system, with particular emphasis on property distribution in relation to bioregional and population centres, was undertaken. Land for Wildlife agreements had greater numbers of properties and total area protected in all bioregions throughout the State, yet average protected area sizes were lower than those of conservation covenants and Trust for Nature reserves. A combination of large bioregional area and human population size tended to attract more private conservation properties and, to a lesser extent, the total area they protected. The potential contribution that such properties made to biodiversity conservation varied between bioregions. Inclusion of properties within a national reserve framework is proposed to improve the coordination and effectiveness of conservation measures.

Buxton silver gum reserve: using geographic information systems to investigate historic change in site integrity

Eucalyptus crenulata is a rare species known from only two populations. The Buxton Silver Gum Reserve was set aside in 1978 for the conservation of the species, but this objective may be compromised by changes in the integrity of the landscape immediately surrounding the Reserve. A time sequence of aerial photos and Geographic Information Systems technology has been used to identify patterns of landscape change, and aid in determining appropriate management strategies to minimize negative impacts caused by landscape fragmentation and habitat exposure

Walkability of local communities: using geographic information systems to objectively assess relevant environmental attributes.

Geographic Information Systems (GIS) can be used to objectively measure features of the built environment that may influence adults’ physical activity, which is an important determinant of chronic disease. We describe how a previously developed index of walkability was operationalised in an Australian context, using available spatial data. The index was used to generate a stratified sampling frame for the selection of households from 32 communities for the PLACE (Physical Activity in Localities and Community Environments) study. GIS data have the potential to be used to construct measures of environmental attributes and to develop indices of walkability for cities, regions or local communities.

Development of a web-based information system for cascading utilisation of construction materials

This paper presents a Web-based information system for promoting the cascading utilisation of construction materials in order to mitigate the increasing environmental pressure by the construction industry. First, this paper points out me weaknesses of current waste material exchange systems. Then, a new approach is introduced to reuse demolished materials, by which the utilisation of demolished materials may be ascertained before the demolition is actually produced.. Information technologies, including web-based intelligent and distributed systems, are applied to actua1ise this approach. Finally, the development and implementation of the system is described in detail.

Deconstructing power within a strategic information system

Strategy is a political act, and yet that has received very little attention in IS strategy research. The purpose of this paper is to explore the mixes between politics, power and strategy using a case study of implementation of a Student Administration System. This takes Strategic Information Systems out of the realm of the purely socia-technical view of information systems and moves it into a dimension which deals with the real social interactions that occur within organisations as a result of the implementation of a strategy in the form of a Student Administration System. This case study shows the power struggles, primarily by two Senior Executives and the users of the information system. The discourse behind this project was initially to create uniformity across a system therefore enabling more than 30 universities around Australia to move from a diversified system to a centralized system. It was through this resistance and through their positions that the two Senior Executives were able to create the discourse that framed many of the decisions and implementation of the system. There eventually became an acceptance that it was for the social good of the University that the Student Administration System was adopted across the University of Australia.

Information system strategy for promoting demolition project management

Building demolition has been undergoing evolutionary development in its technologies for several decades. In order to achieve a high level of demolition material reuse and recycling, new management approaches are also necessitated, in particular in conjunction with the applications of information technologies. The development of an information system for demolition project management is an impactful strategy to support various demolition activities including waste exchange, demolition visualization, and demolition method selection and evaluation. This paper aims to develop a framework of an integrated information system for building demolition project demolition decision-making and waste minimization. The components of this information system and their interactions are demonstrated through a specifical demolition project.

Utilising integrated information system approach for building demolition project management

Building demolition has been undergoing evolutionary development in its technologies for several decades. In order to achieve a high level of demolition material reuse and recycling, new management approaches are also necessitated. Several information systems are proposed or developed particularly promoting efficient project management, waste minimization and project safety. These information systems include waste exchange, 4D visualization, safety aware schedule, waste product schedule, site atTangement optimization and so on. However, the fragmented information systems applied by various parties involved in the demolition project could generate conflicts due to the lack of communication and standardization. This paper aims to develop a framework of an integrated information system for building demolition projects, which covers the major aspects of innovative management approaches and conventional construction project management perspective. Practically, the system will serve as an information portal for all demolition project team members.

Attitudes of Australian information system managers against online attackers

Examines the attitudes of Australian IS/IT managers to the concept of cyber-vigilantism. Also, it explores the policies and procedures which have been set in place by various organisations to cope with concerted attacks on their systems. It finds that although a majority of managers do approve of the concept of “striking back”, only a minority are prepared for this eventuality. There appears to be complacency about the threats posed by organised, offensive attackers.

Measuring the walkability of local communities using geographic information systems data

Researchers are working to identify and promote environment and policy initiatives to encourage more active and healthy communities. Measuring environmental attributes through objective means can verify which physical environment factors are most important. We describe how Geographic Information Systems (GIS) may be used to measure objectively, the features of the built environment that may influence walking. We show how four key attributes currently believed to be of most relevance to walking for transport may be used to create a ‘walkability’ index. These are dwelling density (higher-density neighbourhoods support greater retail and service variety, resulting in shorter, walkable distances between facilities; driving and parking are more difficult); street connectivity (higher intersection density provides people with a greater choice of potential routes, easier access to major roads where public transport is available and shorter times to get to destinations); land use mix (the more varied the land use mix and built form, the more conducive it is to walk to various destinations); and net retail area (people who live near multiple and diverse retail opportunities are able to make more frequent and shorter shopping trips by walking and can walk to more local employment opportunities). The potential relationships between each of the objective environmental-attribute measures and walking behaviours is discussed, together with suggestions as to how such measures might be used to guide community infrastructure planning. GIS mapping can assist decision makers in where to focus transportation investments and where to guide future growth. Readily accessible GIS data can be used to guide and support urban planning and infrastructure investment decisions in both the private and public sectors, to increase walking in communities.
