Knowledge enhancement in the change process : social marketing and attitude change leading to improved environmental behaviour

The complexity of relationships between social change and natural resource management has generated interest in the identification of indicators that might provide more streamlined means of monitoring and planning control programmes. This case study highlights the marketing paradigms of benchmarking and social marketing in a not-for-profit governmental environment. Publicly funded programs that require individual and community participation need to be marketed with a view to optimising involvement and commitment of the various stakeholders. A mail survey with a representative sample of 608 respondents was conducted to evaluate the effectiveness of a social marketing program. This study highlights the use of social marketing in a program to overcome an environmental issue by a governmental agency. Changing attitudes and beliefs takes time and often the target audience may not even know they have a problem that needs fixing. This process influences the focus of the social marketing effort which might be organised into three phases: • Raise awareness and knowledge.   •Change attitudes.  • Encourage action. The research conducted in this study illustrates how the various stages in the social marketing process were achieved through knowledge enhancement in an environmental management case study.

Using knowledge management processes to develop and implement organisational training strategies for virtual teams : an action learning approach

This paper develops a conceptual model of a knowledge management system that could be used to develop and implement organizational training strategies for virtual teams. An action research-based case is presented to support and illustrate the contention that action-learning methods can be effectively used to enable and tap into the knowledge generated by virtual teams. Virtual teams are an increasingly common response to changing organizational needs. However, the use of virtual teams has outpaced our understanding of their dynamics and unique characteristics. Practitioners are now offering virtual team training, but few organizations are making the effort to offer in-house training. Moreover, they are missing out on the opportunity to systematically capture the knowledge produced by virtual teams and cycle it back into virtual team training and support systems.

Government influence on intrinsic and extrinsic motivation in environmental social marketing

There is a need for more effective and efficient social behavioural change programs instigated by public sector environmental management organisations. The concepts of intrinsic motivation and extrinsic motivation have been shown to provide insights into the environmental behaviour of various groups. The aim of the paper is to investigate the relationship between Intrinsic Motivation, Extrinsic Motivation and Government influence. In particular this study examines the inter-relationship between intrinsic and extrinsic motivation in environmental management. A random sample of 566 land managers in South-eastern Australia was obtained. A structural equation model was used to develop a model which identities the relationship between intrinsic motivation, extrinsic motivation and government influence.

Power and politics in a system implementation

The central concern of this study is to identify the role of power and politics in systems implementation. The current literature on systems implementation is typically divided into two areas, process modelling and factor based studies. Process modelling classifies the implementation into a linear process, whereas factor based studies have argued that in order to ‘successfully’ implement a system, particular critical factors are required. This literature misses the complexities involved in systems implementation through the human factors and political nature of systems implementation and is simplistic in its nature and essentially de-contextualises the implementation process. Literature has investigated some aspects of human factors in systems implementation. However, it is believed that these studies have taken a simplistic view of power and politics. It is argued in this thesis that human factors in systems implementation are constantly changing and essentially operating in a dynamic relationship affecting the implementation process. The concept of power relations, as proposed by Foucault (1976, 1977, 1978, 1980, 1982), have been utilised in order to identify the dynamic nature of power and politics. Foucault (1978) argued that power is a dynamic set of relationships constantly changing from one point in time to the next. It is this recognition that is lacking from information systems. Furthermore, these power relations are created through the use of discourse. Discourse represents meaning and social relationships, forming both subjectivity and power relations. Discourses are also the practices of talk, text and argument that continuously form that which actors speak. A post-structuralist view of power as both an obvious and hidden concept has provided the researcher a lens through which the selection and implementation of an enterprise-wide learning management system can be observed. The framework aimed to identify the obvious process of system selection implementation, and then deconstruct that process to expose the hegemonic nature of policy, the reproduction of organisational culture, the emancipation within discourse, and the nature of resistance and power relations. A critical case study of the selection and implementation of an enterprise-wide learning management system at the University of Australia was presented providing an in-depth investigation of the implementation of an enterprise-wide learning management system, spanning five years. This critical case study was analysed using social dramas to distinguish between the front stage issues of power and the hidden discourses underpinning the front stage dramas. The enterprise-wide learning management system implemented in the University of Australia in 2003 is a system which enables academic staff to manage learners, the students, by keeping track of their progress and performance across all types of training activities. Through telling the story of the selection and implementation of an enterprise-wide learning management system at the University of Australia discourses emerged. The key findings from this study have indicated that the system selection and implementation works at two levels. The low level is the selection and implementation process, which operates for the period of the project. The high level is the arena of power and politics, which runs simultaneously to the selection and implementation process. Challenges for power are acted out in the front stage, or public forums between various actors. The social dramas, as they have been described here, are superfluous to the discourse underpinning the front stage. It is the discourse that remains the same throughout the system selection and implementation process, but it is through various social dramas that reflect those discourses. Furthermore, the enactment of policy legitimises power and establishes the discourse, limiting resistance. Additionally, this research has identified the role of the ‘State’ and its influence at the organisational level, which had been previously suggested in education literature (Ball, 1990).

Management of SPMD based parallel processing on clusters of workstations

Current attempts to manage parallel applications on Clusters of Workstations (COWs) have either generally followed the parallel execution environment approach or been extensions to existing network operating systems, both of which do not provide complete or satisfactory solutions. The efficient and transparent management of parallelism within the COW environment requires enhanced methods of process instantiation, mapping of parallel process to workstations, maintenance of process relationships, process communication facilities, and process coordination mechanisms. The aim of this research is to synthesise, design, develop and experimentally study a system capable of efficiently and transparently managing SPMD parallelism on a COW. This system should both improve the performance of SPMD based parallel programs and relieve the programmer from the involvement into parallelism management in order to allow them to concentrate on application programming. It is also the aim of this research to show that such a system, to achieve these objectives, is best achieved by adding new special services and exploiting the existing services of a client/server and microkernel based distributed operating system. To achieve these goals the research methods of the experimental computer science should be employed. In order to specify the scope of this project, this work investigated the issues related to parallel processing on COWs and surveyed a number of relevant systems including PVM, NOW and MOSIX. It was shown that although the MOSIX system provide a number of good services related to parallelism management, none of the system forms a complete solution. The problems identified with these systems include: instantiation services that are not suited to parallel processing; duplication of services between the parallelism management environment and the operating system; and poor levels of transparency. A high performance and transparent system capable of managing the execution of SPMD parallel applications was synthesised and the specific services of process instantiation, process mapping and process interaction detailed. The process instantiation service designed here provides the capability to instantiate parallel processes using either creation or duplication methods and also supports multiple and group based instantiation which is specifically design for SPMD parallel processing. The process mapping service provides the combination of process allocation and dynamic load balancing to ensure the load of a COW remains balanced not only at the time a parallel program is initialised but also during the execution of the program. The process interaction service guarantees to maintain transparently process relationships, communications and coordination services between parallel processes regardless of their location within the COW. The combination of these services provides an original architecture and organisation of a system that is capable of fully managing the execution of SPMD parallel applications on a COW. A logical design of a parallelism management system was developed derived from the synthesised system and was shown that it should ideally be based on a distributed operating system employing the client server model. The client/server based distributed operating system provides the level of transparency, modularity and flexibility necessary for a complete parallelism management system. The services identified in the synthesised system have been mapped to a set of server processes including: Process Instantiation Server providing advanced multiple and group based process creation and duplication; Process Mapping Server combining load collection, process allocation and dynamic load balancing services; and Process Interaction Server providing transparent interprocess communication and coordination. A Process Migration Server was also identified as vital to support both the instantiation and mapping servers. The RHODOS client/server and microkernel based distributed operating system was selected to carry out research into the detailed design and to be used for the implementation this parallelism management system. RHODOS was enhanced to provide the required servers and resulted in the development of the REX Manager, Global Scheduler and Process Migration Manager to provide the services of process instantiation, mapping and migration, respectively. The process interaction services were already provided within RHODOS and only required some extensions to the existing Process Manager and IPC Managers. Through a variety of experiments it was shown that when this system was used to support the execution of SPMD parallel applications the overall execution times were improved, especially when multiple and group based instantiation services are employed. The RHODOS PMS was also shown to greatly reduce the programming burden experienced by users when writing SPMD parallel applications by providing a small set of powerful primitives specially designed to support parallel processing. The system was also shown to be applicable and has been used in a variety of other research areas such as Distributed Shared Memory, Parallelising Compilers and assisting the port of PVM to the RHODOS system. The RHODOS Parallelism Management System (PMS) provides a unique and creative solution to the problem of transparently and efficiently controlling the execution of SPMD parallel applications on COWs. Combining advanced services such as multiple and group based process creation and duplication; combined process allocation and dynamic load balancing; and complete COW wide transparency produces a totally new system that addresses many of the problems not addressed in other systems.

An integrated observation network for the Gippsland Lakes, Victoria, Australia : balancing the needs of science and management

The Gippsland Lakes region in eastern Victoria is a partially flushed coastal lake system within a diverse catchment of rural and urban communities. Pressure from lakeside developments, re-occurring blue-green algal blooms, declining fisheries, sedimentation and infilling of the ocean entrance, has borne several decades of focussed studies and routine monitoring programs, along with a variety of engineering and management solutions. A recent review recommended that these disparate studies should be enhanced to formulate a coordinated monitoring network that could improve both spatial and temporal coverage, develop a capacity to trigger responsive investigations and was able to serve the needs of system management. Through a series of partnerships an integrated network was developed that comprises event and baseline monitoring of catchment loads, local meteorological forcing and an array of water quality sampling sites within the lakes system. A majority of these sites are incorporated with real-time telemetry that provides up to the minute information to stakeholders via a web-based information management system and vital operational status to technical system management.

Development and evaluation of a metadata system for biophysical estuarine data

Biophysical investigations of estuaries require a diversity of tasks to be undertaken by a number of disciplines leading to a range of data requirements and dataflow pathways. Technology changes relating to data collection and storage have lead to the need for metadata systems that describe the vast amounts of data now able to be stored electronically. Such a system is described as the first step in the creation of an efficient data management system for biophysical estuarine data.

Risk-based trust management for e-commerce

Electronic commerce (e-commerce) offers enormous opportunities for online trading while at the same time presenting potential risks. Although various mechanisms have been developed to elevate trust in e-commerce, research shows that shoppers continue to be skeptical about buying online and lack of trust is often cited as the main reason for it. Thus, enhancing success in e-commerce requires eliminating or reducing the risks. In this chapter, we present a multi-attribute trust management model that incorporates trust, transaction costs and product warranties. The new trust management system enables potential buyers to determine the risk level of a product before committing to proceed with the transaction. This is useful to online buyers as it allows them to be aware of the risk level and subsequently take the appropriate actions to minimize potential risks before engaging in risky businesses. Results of various simulation experiments show that the proposed multi-attribute trust management system can be highly effective in identifying risky transaction in electronic market places.

What can Australia learn from the Europeans about public participation? Article 6 of the Aarhus Convention and environmental impact statements

The United Nations Economic Commission for Europe Convention on Access to Information, Public Participation in Decision-Making and Access to Justice in Environmental Matters (Aarhus Convention) is the only international convention that is exclusively devoted to public participation in environmental matters. Although it is European in origin, much of the detail of the Convention draws upon national environmental legislation, including aspects of the Australian environmental legal system. This article compares the public review provisions relating to environmental impact statements in Australia with Art 6 of the Convention governing "Public Participation in Decisions on Specific Activities". The article finds that much of the Australian laws with some exceptions satisfy the minimum requirements of public participation in Art 6.

Working outside of the system

The Deakin Studies Online (DSO) Learning Management System (LMS) forms the fundamental basis for tertiary education at Deakin University. This LMS is founded on Web 1.0 principles, however significant potential exists for engagement in Web 2.0 technologies to support learning and teaching in the design studio. A digitally enhanced design curriculum is discussed starting with html-based reflective folios in 2001, the use of blogs for reflection and resource creation and culminating in a Web 2.0 design studio based on social networking.

An enhanced watermarking protocol for electronic copyright management

In Piva et al's watermarking scheme for electronic copyright management system (ECMS), authors were considered trusted potentially, so a dishonest author could authorize more than one distributor to sell her one document, named "One Document to Multi-distributor" problem, which would damage the benefit of the distributors. To resolve the problem, in this paper, we propose an enhanced watermarking protocol based on Piva et al's scheme by introducing document nature code (DNC) and register records table. In addition, our protocol offers the distributor an efficient means to verify his right to an authorized digital document.

Knowledge management culture, strategy and process in Malaysian firms

Malaysia is one of the leading countries in Asia that are at the forefront in the development of a knowledge-based economy (KBE). The Malaysian government has been making substantial investments in both physical and technological infrastructure to facilitate knowledge-intensive economic activities. Foreign and local firms in Malaysia are encouraged to take advantage of the opportunities brought by the emerging KBE. However, little is known as to how firms in Malaysia respond to this new trajectory of economic development. In particular, there is paucity in the literature as to how Malaysian firms manage knowledge in their organizations as they strive to achieve sustainable competitive performance. Little is known as to how and why firms in Malaysia develop and manage their intangible and knowledge-based resources as they operate and respond to the modern knowledge-based competitive economic arena. This paper examines a type of organizational culture that supports and promotes knowledge management (KM) within firms in Malaysia. The paper argues that KM-oriented culture shapes the overall KM strategy of firms, which consequently shapes the organizational process required to manage the firm's knowledge-based resources. The study uses survey data from a sample of 153 firms from Malaysia. Structural equation modelling was used to develop and test the measurement model of KM-oriented culture, KM strategy and KM process of the sample firms, as well as the structural model of their hypothesized relationships. The results show that firms with high level of KM-oriented culture demonstrated well-defined KM strategies. Firms that implemented well-defined KM strategies also reported that they have better KM processes in place. Building a KM-oriented culture within the organization is a pre-requisite to the implementation of any KM systems in Malaysian firms. Successful implementation of KM strategies, processes and the supporting technological infrastructure depends on whether organizational members consider KM as a norm within the firm. The study's focus on the linkages between KM-oriented culture, strategy and process in the context of Malaysian firms contributes to a more nuanced understanding of KM among firms in the Asian context in general, and in the Malaysian context in particular.

Linking water-resource models to ecosystem-response models to guide water-resource planning -- an example from the Murray--Darling Basin, Australia

Objectively assessing ecological benefits of competing watering strategies is difficult. We present a framework of coupled models to compare scenarios, using the Coorong, the estuary for the MurrayDarling River system in South Australia, as a case study. The framework links outputs from recent modelling of the effects of climate change on water availability across the MurrayDarling Basin to a hydrodynamic model for the Coorong, and then an ecosystem-response model. The approach has significant advantages, including the following: (1) evaluating management actions is straightforward because of relatively tight coupling between impacts on hydrology and ecology; (2) scenarios of 111 years reveal the impacts of realistic climatic and flow variability on Coorong ecology; and (3) ecological impact is represented in the model by a series of ecosystem states, integrating across many organisms, not just iconic species. We applied the approach to four flow scenarios, comparing conditions without development, current water-use levels, and two predicted future climate scenarios. Simulation produced a range of hydrodynamic conditions and consequent distributions of ecosystem states, allowing managers to compare scenarios. This approach could be used with many climates and/or management actions for optimisation of flow delivery to environmental assets.
