Australia and Japan in the South Pacific island countries : a general appraisal through the concepts of structural power

This study examines several specific fields of activity of Australia and Japan in the areas of security, production, finance, development assistance, information, education and regional organization. Using the concept of structural power, it observes the sources of Australian and Japanese strenght in the region, the growing imbalance in the bilateral Australia-Japan relationship, and also the coexistence of affinities and differences in the development opportunities opened to the South Pacific Island Countries.

Understanding Concepts of Efficiency and Effectiveness in Architectural Facilities Space Planning and Design

Although contemporary literature treats efficiency and effectiveness extensively, virtually no objective understanding of both is found in architectural facilities space planning and design. It is imperative that both concepts are definitively explained as they apply to these disciplines. Hence, the contemporary views of both concepts are reviewed and attempts made to interpret them within more amenable contexts. The objectives are (1) to objectively elucidate the factual differences between efficiency and effectiveness; and (2) to contribute to their better understanding in architectural facilities space planning and design. Diagrammatic and mathematical means are engaged to demonstrate efficiency and effectiveness in these fields.

Deaf education and underlying structures of power in communication

This article argues that claims of diversity in communication in deaf education are empty rhetoric when underlying structures of power are unexamined and remain unchanged. The field of deafness provides a powerful example of the way in which competing interests can be played out under the guise of choice of communication methods. Historically, teachers of the deaf have been divided about whether deaf children should be educated through speech or sign. However, recognition of the legitimacy of native sign languages has caused a shift in the debate to the linguistic basis of this communication and the way in which language policy privileges one cultural group and its method of communication over another.

Distribution of power requirements during yarn winding in ring spinning

A model of a yam package is established for a ring spinning system. The yarn layer, surface area, and mass of the yam package are formulated with respect to the diameters of the empty bobbin and full yarn package, yarn count, and yarn winding-on time. Based on the principles of dynamics and aerodynamics, models of the power requirements for overcoming the skin friction drag, increasing the kinetic energy of the yarn package (bobbin and wound yarn), and overcoming the yarn wind-on tension are developed. The skin friction coefficient on the surface of a rotating yam package is obtained from experiment. The power distribution during yam packaging is discussed based on a case study. The results indicate that overcoming the skin friction drag during yarn winding consumes the largest amount of energy. The energy required to overcome the yarn wind-on tension is also significant.

Capitalizing on Bourdieu : how useful are concepts of `social capital` and `social field` for researching `marginalized` young women?

This article considers Bourdieu’s concepts of ‘social capital’ and ‘social fields’, comparing and contrasting his use of these concepts with that of James Coleman and Robert Putnam. It examines how Bourdieu’s ideas offer a different way of understanding the lives of economically disadvantaged young women designated as ‘at risk’ of leaving school early. A micro-level analysis is made of ‘Bluey’s story’, a narrative derived from data gathered during a three-year research project on young women’s negotiations from the margins of education and work in Australia. Deconstructing Bluey’s narrative reveals how social capital is deployed (sometimes unsuccessfully) in a range of social fields. Such narratives can thus be used to ‘speak back’ to educational policies, to provide alternative insights into the issues and needs of economically disadvantaged young women and to challenge current constructs of ‘at risk’.

Application of neural networks as an auxiliary technique in the modelling of power station

Artificial neural network (NN) is an alternative way (to conventional physical or chemical based modeling technique) to solve complex ill-defined problems. Neural networks trained from historical data are able to handle nonlinear problems and to find the relationship between input data and output data when there is no obvious one between them. Neural Networks has been successfully used in control, robotic, pattern recognition, forecasting areas. This paper presents an application of neural networks in finding some key factors eg. heat loss factor in power station modeling process. In the conventional modeling of power station, these factors such as heat loss are normally determined by experience or “rule of thumb”. To get an accurate estimation of these factors special experiment needs to be carried out and is a very time consuming process. In this paper the neural networks (technique) is used to assist this difficult conventional modeling process. The historical data from a real running brown coal power station in Victoria has been used to train the neural network model and the outcomes of the trained NN model will be used to determine the factors in the conventional energy modeling of the power stations that is under the development as a part of an on-going ARC Linkage project aiming to detail modeling the internal energy flows in the power station.

Framing the discourses of harm and loss: a case study of power relations, mobile phones, and children in Australia

The current penetration of mobile phones in Australia is 92% and it records one of the world’s highest rates of ownership among children under 18. The paper reviews the literature on mobile phones and Australian children and examines the various discourses dominating the public debates; the systematic frames used in these discourses; and whose interests are served in the process. The frames discussed fall under the optimistic (gains); pessimistic (losses, costs or harms); pluralistic (technology per se is neutral but how it is used matters); historical development (skills learnt and the importance of using mobiles); futuristic predictions (promises and dangers for the future); current uses (connectivity, convergence and interactivity); and the techno-realist view (as a mixed blessing) views of technology. Taking the critical perspective and borrowing from Joshua Meyrowitz, the paper illustrates how mobile phones have eroded parental power over how, when, where and with whom their children communicate, surpassing adult supervision, intervention or knowledge, while at the same time, becoming a ‘digital leash’ for parents to re-establish their control an d an ‘umbilical cord’ for their off spring to remain connect! ed with parents, at all times.

'Research as dialogue' and cross-cultural consultations : confronting relations of power

ln this paper, we discuss methodological issues that emerged as we worked through a small empirical research project, 'Engaging Aboriginal students in education through community empowerment'. Recent national policy statements (see, for example, MCEETYA 2000,. NBEET 1995) argue the importance of education/research that keeps the locus of control within the Aboriginal community as a means to further the goal of self-determination and improve educational outcomes. In keeping with these recommendations, our project aimed to challenge assimilationist frameworks and sought to 'empower' members of the local Aboriginal community through participation in the project. 'Research as dialogue' was a guiding principal and a primary aim was to listen actively to all key stakeholders in the remote community setting, particularly to lndigenous parents, students and teachers, in order to identify current strengths and concerns regarding the provision of culturally inclusive schooling. A proposed second stage of the project is to develop, on the basis of these consultations and in collaboration, community-based education projects that engage non-attending Aboriginal students. Here we discuss the consultative processes undertaken in stage one of the project, and critically analyse the difficulties as well as potential strengths of trying to form collaborative partnerships as researchers across cultural differences and with diverse community groups.

Perceptions of power and dependence between retail buyers and fresh produce suppliers within the Australian fresh produce industry

The research aims to gain a deeper understanding of direct buyer-supplier relationships within the Australian fresh produce industry. Specifically, dependence and power within the buyer-supplier relationship are considered in terms of their antecedents and their relationships their-in. In-depth interviews with buyers and suppliers provided the means by which to expose perceptions with regard to the relative importance of dependence and power within the relationship. The research reveals that relationship antecedents (trading offer: price and quality) impact power and dependence and are, in tum, impacted by them.
