This paper describes a study of educators at an Australian University who are using eTechnolo-gies in their teaching. The perceptions of the educators of the technologies are discussed as well as how they believe these technologies help students to learn. Outcomes from the study offer suggestions of how appropriate eTechnologies can be incorporated into online learning environments for effective teaching. Particular emphasis is made of eTechnologies which support active learning by students, one of the goals of the principles of good teaching practice in undergraduate education.

This paper examines the adoption and development of intranets in large business organizations. The authors demonstrate that intranet technology introduces a host of new managerial and technical challenges and requires new approaches to IS development. Evidence from two European corporations indicates that the traditional division of labor and definition of work roles in IS development breaks down. The distinction between developers and users becomes increasingly blurred and new organizational roles and structures associated with intranets are emerging. However, ready-made organizational models for implementing and managing intranets do not exist and the two organizations in this study have followed two different approaches. One organization favors a “planned change” approach, emphasizing management control and careful planning. The other organization prefers an “improvisational” approach, emphasizing experimentation, innovation and local initiative.

Water reuse has become an integral element of the "total water resources planning and management" along with the other elements such as water conservation, water use efficiency and management of the allocation of existing water sources. Researchers are working actively on the following aspects of water reuse: identification and characterization of different wastewaters that could be reclaimed, development of treatment technologies and effluent standards, quantification of potential gains due to recycling and risk management. The wastewaters that can be reclaimed are domestic and industrial wastewaters, grey water, black water, stormwater and rain water and their potential reuse lies in agriculture, aquaculture, industries, non-potable use in residential and community fronts and indirect and direct potable use. The treatment of wastewater ranges from secondary treatment to advanced treatment, which produces different "Classes" of reclaimed water. This paper evaluates the current status of the research on the above-mentioned important aspects of water reuse with relevant case studies and the future demand for reuse water. The direction in which the future-reuse schemes should be formulated so that they are safe, environmentally sustainable and cost effective are also discussed.

A passion for food that is understood in certain ways – slow, organic, not industrialised – plays a central role in the drama of the successful and popular Jamie’s Kitchen (2002) and Jamie’s Kitchen Australia (2006). Large parts of the drama in these shows revolve around an apparent lack of passion that is displayed by the marginalised, unemployed young people that are the central characters in this story. In this paper I examine the ways in which these accounts of food, passion, and the training of marginalised young people expose some of the challenges and opportunities faced by marginalised young people as they seek to transition into the uncertain and risky labour markets of 21st century capitalism. I argue that Michel Foucault’s (1988) concept of technologies of the self enables us to understand passion, and its particular manifestations in Jamie’s Kitchen, and in the training of marginalised young people, as a powerful technology of self transformation. The drama of Jamie’s Kitchen suggests that as a technology of the self passion for food promises to provide precarious, possibly temporary, forms of salvation, meaning and purpose for the young people engaged in the Fifteen Foundation’s social enterprise transitional labour market program.

The last decade has delivered substantial changes in construction and property education in Australia and the UK. There has been an increase in the number of courses offered in built environment education and the profile of a typical student has changed. In both countries students are under pressure to balance study and work due to the higher costs of living and education. This has placed demands on providers to deliver teaching and learning which meets student, industry and professional needs. Simultaneously there has been an increase in the application of technology in the business and corporate world which has resulted in increased efficiencies and new challenges. This paper evaluates changes in construction and property education courses to embrace new technology. The focus is on the delivery of innovative teaching and learning materials and the interaction between students, staff and the community. Results from questionnaires from new and existing students at Deakin University and Nottingham Trent University were used alongside examples of teaching and learning as illustrative case studies, the emphasis is placed on pushing the boundaries of the conventional built environment education process. The findings show that by embracing technology there can be a „win-win‟ scenario for students, staff and industry stakeholders. Whilst courses adopt varying levels of technology, it seems inevitable that educators must evolve the delivery of education to become efficient and effective as the century progresses.

The discovery that an impressively strong 3-dimensional effect in a 2-dimensional photographic representation of natural outdoor scenes occurs when a single camera is directed around one point in the scene, thus drawing into relief the subject of attention and blurring the surrounding space, has important implications for understanding basic processes in 3-dimensional vision. For the development of new ways for generating 3D effects in motion and static representations of scenes we might well learn from photography’s old technologies, as well as digital technologies of the static print, which have yet to release the full impact of their potential in the representation of motion and space.

Agro-industries are a life-line for sustainable future of human kind. However, the wastewater generated by agro-industries poses direct threat to the same sustainable future by polluting the freshwater sources when discharged into those freshwater sources. Thus, we need both advanced treatment technologies to treat those wastewater streams generated and better reuse practices for the treated effluents. Reverse osmosis (RO) is one of the advanced treatments to treat dissolved solids that are present in agricultural wastewater streams. But, RO is very sensitive to suspended solids (SS) present in the wastewater streams. Those SS can foul the RO membrane and make it ineffective in producing treated effluent at desired rates. Therefore, suitable pre-treatment scheme is necessary to treat the agro-wastewater streams before passing through RO. This study focuses on the qualitative and quantitative ranking of the available conventional and modern pre-treatment technologies as pre-treatment for RO. This study considers wastewater that has been treated through a secondary treatment system for example activated sludge process as the target water that needs pre-treatment. Based on qualitative ranking of conventional pre-treatment options, the Lime clarification/Granular Media filtration (GMF) option is ranked as the best; whereas finescreens/ micro-screens option ranked as the least preferred option based on the scores they attained in treating the water quality parameters that are considered essential. Based on the quantitative ranking, the low pressure membrane technology such as ultra-filtration (UF) stood first and microfiltration (MF) stood last.

In contrast to the international research (particularly in the United Kingdom and North America), much of the Australian literature regarding homelessness to date omits the perspective of people who are homeless. In contributing to the fledgling Australian literature in the field, the following article adopts a secondary approach to the data analysis of original research. When analysed, the voices of homeless women from an agency in Adelaide, South Australia exhibit elements of both Foucault’s technologies of domination and the self. While the results show that the women do have a powerful sense of the broader external issues exerted on them (reflecting both technologies of domination and the self), the analysis also reveals ambiguities in their responses. Apparent in the voice of homeless women is a sense of personal agency which appears to be absent in Foucault’s technologies. By considering the viewpoints of homeless women, various policy implications can also be drawn. Indeed, this is one of the motivations of the article, namely to inject into policy debate and development the voices of the people most adversely affected by it. The policy implications of the women’s voices centre around the desire to be included rather than remain on the margins, the need for supportive relationships, the necessity to take small steps to independent living, and the need for more affordable, independent housing.

This paper has been prepared to address the issues and questions of the theme ‘access, equity and socio-cultural issues’. Findings from two studies are reported. In the first study gender issues in mathematical learning environments when computers were used were investigated. In the second effective practices for teaching disadvantaged or marginalised students with digital technology are canvassed. Teaching for equity and social justice in the digital age is complex. Teachers need to be aware that their beliefs and classroom practices may exacerbate gender and cultural inequalities in mathematics learning. Approaches that are consistent with social-constructivist and democratic theories need further investigation.

In this paper the pedagogical practices of practising teachers and pre- service teachers when using digital technologies are described and compared. Data were collected by observation of presentations about using digital technology in mathematics by teachers and pre-service teachers and practising teachers were interviewed. Teachers generally used pedagogical approaches involving student-centred activity whereas pre-service teachers were more likely to use technology to teach concepts by demonstration and were not inclined to use the more student- centred approaches, though many used guided tasks. The study enabled some analysis and reflection upon the promoted action in the learning environments of pre-service teachers.

The number of different e-learning technologies available to support teaching and learning is growing exponentially. A major issue for faculty and educational developers in higher education is to determine which e-learning technology is most appropriate to support their particular teaching needs and provide optimum learning opportunities for students. Over the last few years a vast amount of literature has been published on e-learning technologies and how they are used in education Therefore the decision to use a particular technology should be based on sound research and clear evidence. This paper reviews many of these e-learning technologies and provides information regarding their use and the opportunities afforded by them.
