In their out-of-school lives, young people are immersed in rich and complex digital worlds, characterised by image and multimodality. Computer games in particular present young people with specific narrative genres and textual forms: contexts in which meaning is constructed interactively and drawing explicitly on a wide range of design elements including sound, image, gesture, symbol, colour and so on. As English curriculum seeks to address the changing nature of literacy, challenges are raised, particularly with respect to the ways in which multimodal texts might be incorporated alongside print based forms of literacy. Questions focus both on the ways in which such texts might be created, studied and assessed, and on the implications of the introduction of such texts for print based literacies.

This paper explores intersections between writing and computer games within the English classroom, from a number of junior secondary examples. In particular it considers tensions that arise when young people use writing to recreate or respond to multimodal forms. It explores ways in which writing is stretched and challenged by enterprises such as these, ways in which students utilise and adapt print based modes to represent multimodal forms of narrative, and how teachers and curriculum might respond. Consideration is given to the challenges posed to teaching and assessment by bringing writing to bear as the medium of analysis of, and response to, multimodal texts.

The fake presupposes the genuine. The fake author implies the real author, and fake literature presupposes real literature. But literature itself is often about— perhaps fundamentally about—successfully faking it. However, the concern and hostility with which literary public culture has responded to fake authors and what is deemed to be their “fake” literature suggests that the notions of real authors and literature remain centrally important.

The interactions between cage culture and wild fishery activities in three Indonesian reservoirs, Saguling, Cirata and Jatiluhur, of the greater Ciratum watershed, West Java, were evaluated using historical data and interviews with cage culture operators. In all three reservoirs, cage culture of common carp, Cyprinus carpio L., and later of common carp and Nile tilapia, Oreochromis niloticus (L.), were encouraged as an alternative livelihood for persons displaced by the impoundment. Currently, a two-net culture system, locally known as 'lapis dua', in which in the inner cage (7 × 7 × 3 m) is used for common carp culture and the outer cage (7 × 7 × 5/7 m) is stocked with Nile tilapia, is practised. On average each cage is stocked with  approximately 100 kg fingerlings each of common carp and Nile tilapia. The numbers of cages and production of cultured fish has increased in the reservoirs, but total and per cage production began to decline from about 1995 in Saguling from 2200 kg cage−1 in 1989 to <500 kg cage−1 in 2002, and in Cirata from a peak of approximately 2300 kg cage−1 in 1995 to approximately 400 kg cage−1 in 2002. In Jatiluhur, which has a considerably lower cage density, total fish production and production per cage has increased since 2000, and currently is approximately 4000 kg cage−1, close to production in the early years of cage culture activities. The cage culture operations also resulted in substantial nutrient loading, estimated at 3.2, 15.2 and 3.1 t of nitrogen and 134, 636 and 128 kg of phosphorous per year in the maximum years of production for Saguling, Cirata and Jatiluhur reservoirs, respectively. In later years, when cage culture production was high, fish kills occurred in the cages, and in Jatiluhur reservoir coincided with a dramatic decline in wild fishery catches. An attempt is made to determine the maximum number of cages for each of the reservoirs that will bring long-term sustainability of cage culture operations and the wild fisheries in the three reservoirs.

This paper argues that the nature of IS research that deals with indigenous culture must be informed as much by context as it is by culture models, which has been the focus of such research in the past. This is considered important because it better reflects the meaning of the data collected for the researcher. To appreciate the importance of context this papers also argues that research subjects from designated individualist societies will inform the researcher in different ways from those subjects located in collectivist societies. To illustrate the practical implications of this argument the paper reports three separate case studies in IS research where the researchers reflect on the impact that a collectivist view has had on the research findings. The paper suggests that (1) similar ethnicity and appearance are significant in gaining the trust of subjects in a collectivist society; that is the researcher is part of the in-group as they belong to the same culture or ethnic group; that (2) who introduced the researcher to the subject is significant in that trust is best reflected when a member of the group/collective plays an important role in the research process itself; and that (3) an ability to (a) communicate in the natural language and (b) understand the implicit body language and (c) cultural codes is important in gaining significant and more meaningful research outcomes. This is enabled via the implicit meanings embedded in members of the collectivist society.

This paper outlines an exploratory research project that draws on survey data from both primary and secondary school music teachers in Victoria. The research stems from a study that I undertook in 2002-2003 with final year Deakin University undergraduate students. That project investigated the potential of African music to enhance the generic musical experiences, learning, motivation, interest, confidence and competence of non-specialist primary teacher education students. The research project being reported in this paper is an extension of the previous study to focus on practising music teachers at both primary and secondary school levels. The research addresses the significance and contribution of African music and culture as a cross-cultural experience for music teachers, their students and the wider community. It further considers my role as an African music practitioner in terms of transformation and acculturation. This paper outlines the progress of, and provides preliminary data about, the emergence of an innovative area of teaching and learning based on African music in Victorian schools. It also explores the notion of why cross-cultural and multi-cultural engagement matters in the contemporary context of educational change.

There is expanding interest in the culture of the Australian shortfin eel Anguilla australis Richardson; however, there is a lack of fundamental biology and husbandry information necessary to further develop an industry within Australia. The present study was undertaken to gain a preliminary understanding of basic husbandry requirements for rearing of juvenile A. australis (glass eels and elvers) in tanks and earthen ponds. Newly caught glass eels were successfully acclimated to culture conditions. During tank culture trials, specific growth rates (SGR) and survival rates ranged from −2.1 to 2.8% day−1 and 52% to 100% respectively. Glass eels weaned onto a commercial eel diet exhibited a significantly greater SGR and survival rate than those weaned onto a commercial trout diet. Glass eels weaned onto an eel diet over a 15-day period grew slightly faster than eels weaned over a 5-day period, but survival rates were not significantly different for each treatment. SGRs (up to 2.8% day−1) were significantly higher for glass eels fed at 9 and 12% day−1 than at 6% day−1. Stocking densities between 2.5 kg m−3 and 30 kg m−3 did not influence either SGR or survival rates. SGRs were significantly higher for glass eels cultured at 25 °C than at lower temperatures. During pond culture trials, SGRs and survival rates ranged from 1.36 to 1.65% day−1 and 39% to 77% respectively. The SGR and survival rates of juvenile eels stocked into ponds receiving supplementary feeding with a commercial eel diet were not significantly different to those of eels stocked into ponds that did not receive supplementary feeding.

The role of the human resource management (HRM) function and its consequent contribution to organizational culture and strategic management have been much debated. This relationship has not been empirically tested in the Australian local government sector. This paper explores the types of organizational culture and the role effectiveness of the HRM function as perceived by 217 senior managers in 71 New South Wales and Queensland local government entities. We found four clusters of local government entities, each with different profiles of organizational culture and perceived effectiveness of the HRM role. While most organizations are undergoing a transition in their cultural values, over one-third of the organizations exhibit a market-oriented culture. These market-oriented organizations have a higher level of human resource role effectiveness. The present study contributes to the ongoing debate regarding the status and influence of HRM as a value-adding corporate function.

Community Development as a form of practice promotes empowerment and social justice. Its origins lie in people's collective struggle to be heard, recognised and accorded full citizenship in society. It has developed strategies to achieve social change that challenge dominant ways of thinking, policy and resource allocation in society. 'Enterprise culture has its origins in the individualism and competitiveness of capitalism. These essentially neo-liberalist concepts have been remoulded into a radical political program of change sponsored by the state under the guise of new managerialism, competitive tendering and privatization. This research seeks to examine the interface between community development and enterprise culture as a potential site of tension and contestation through an analysis of discourse. The initial task, therefore, was to elaborate the concept of enterprise culture and examine the ways enterprise culture has been manifested in community development. The focus has been on practitioners committed to community development through a qualitative, empirical approach with a view to discerning their views on the relevance and impact of enterprise culture on their work. Community development provides a useful domain for interrogating the infiltration of the concept of the enterprise culture because of its history of opposition and mobilisation. The research seeks to understand the ways in which the forms of enterprise culture as an essentially cultural project are manifested in practice contexts and to analyse the nature of the response to its various manifestations. As a result, it constitutes more than just a critique of any one of these forms, eg, privatisation, tendering out, managerialism, and instead seeks to investigate the degree to which a cultural shift may be occurring towards notions of greater individualism and away from collective notions of responsibility, obligation and citizenship. The research critically analyses the impact of enterprise culture on Australian social policy through the case study of community development practice. The manifestations of enterprise culture are investigated at various levels, with an emphasis on the responses of practitioners. A related aim is to reveal the range of possible responses to the infiltration of the enterprise culture in terms of values, language and practice into community development. Are new forms of practice emerging or is the field being steadily co-opted by government social and educational policy? Finally, the research should enable some future directions to be identified for the field of community development. The findings represent an initial attempt in an Australian context to establish the degree of influence that enterprise culture has had and/or will have on social policy. Chapter 1 examines the concept of enterprise culture and a background to its impact on community development as a domain of practice. The meaning of enterprise culture and its origins will be examined in Chapter 2. Its influence on Australian social policy is then discussed with particular reference to recent changes in Victoria regarding family services. In Chapter 3, the main features of critical discourse analysis are outlined as a framework for subsequent analysis of the links between discourse and hegemony. The work of Fairclough (1992, 1995) is utilised to highlight the relevance of discourse analysis to an examination of the infiltration of ideas associated with enterprise culture into the domain of community development. Chapter 4 provides an overview of the origins and defining characteristics of community development practice. The diverse beginnings and philosophical underpinnings are discussed and the main features of community development outlined in order to establish meanings attached to key concepts such as empowerment and participation. In Chapter 5, the findings of initial interviews with sixteen community development practitioners are discussed in terms of their perceptions of the impact of enterprise culture on their practice and the organisational culture within which they operate. These initial interviews were conducted in November-December 1996. A primary focus of the interviews was to establish the key words in their lexicon of practice and to provide an opportunity for reflection on the relative influence of discourse and practices associated with enterprise culture. A framework for analysing and making sense of the forms of response to enterprise culture is applied to the responses. Four forms of possible response are proposed and discussed in the context of the data. Follow up interviews were conducted in November-December 1997 and the findings of these interviews are discussed in Chapter 6. A particular emphasis in these interviews was on any changes in the lexicon of practice and indications of a change in the impact of discourse and practices associated with enterprise culture. The forms of response suggested in the framework outlined in Chapter 5 are discussed in the light of any movement in the responses of participants in the study. The implications of the findings are discussed in the context of the framework of responses or forms of embrace of enterprise culture analysed in earlier chapters. Finally, in Chapter 7, the potential for community development as a form of practice to transcend or at least accommodate the impact of enterprise culture through strategic forms of embrace is discussed and possible strategies based on the research that may assist in the development of this response are proposed.
