Debates continue about the relative benefits, costs and risks of the diffusion of computer-based technologies throughout society and schooling. One area that has received considerable attention is gender equity. Early work on gender and computers focused on differences between male and female access and use (e.g. Huff, Fleming & Cooper, 1992; Kirkman, 1993; Morritt, 1997; Nelson & Cooper, 1997; Sofia, 1993), with concerns focused on the potential for girls to be disadvantaged. In some respects, it is arguable that problems of gender equity in schools with respect to computers have been overcome. For example, in a small study I conducted in two New Zealand senior primary classrooms in 2003, I found that both boys and girls were motivated to use computers and appeared to have equal opportunities to access computers in the classroom. The students in my study expressed a belief in the importance of using computers, and this belief can also be discerned from educational policy and media coverage.
In this paper I argue that, although gender by itself no longer appears to be a source of disadvantage in terms of access to and use of computers in schools, many questions about technology, schooling and power relations still remain unanswered. I present two alternative viewpoints on the new digital age. First, I explore Melanie Stewart Millar’s (1998) analysis of digital discourse as one which reproduces the power of white, middle-class, educated, well-paid males, and excludes anything else it considers ‘Other’. Second, I review arguments that the digital age has provided sites for the transcendence of traditional hierarchies and inequalities (e.g. Spender, 1995). I conclude that, despite the discrepancies between these two viewpoints, both concur that technological disadvantage will exacerbate any existing inequality that might result from intersections of identity categories, such as, gender, ethnicity, age, and socio-economic status.

The current paper discusses the applicability of an online manual for the teaching of first year psychology laboratory programs and compares it with conventional teaching methods. For the first time, in 2001, the manual for the first year program was made available via a website. This method was in contrast to the text manual that was utilised previously. When the text manual was used, students needed to bring it each week to class. However, with the online manual, students were required to be cognisant of several aspects of the week's laboratory agenda prior to attending the class and did not have immediate access to the manual in class. This was quite uncustomary to both students and staff members and therefore necessitated a great amount of time to be spent reviewing the contents of the week's work before attending class. It also caused inconvenience both in terms of students not having ready access to necessary information, and staff having to photocopy bulk information as and when required. What was discovered at the end of the semester was that a technological tool, because of its ability to provide easy access, may not be applicable to teach all subjects, particularly not the psychology lab program, and hence a thorough evaluation of the practicality of the device is required prior to adoption.

Dietary intake of fats and sterols has long been known to play a critical role in human health. High proportions of saturated fat, which increase blood cholesterol levels, are mainly found in animal fat and some plant oil (e.g. cocoa butter, palm oil etc.). The predominant polyunsaturated fatty acid (PUFA) in the Western diet is linoleic acid (LA; 18:2n-6), an essential fatty acid, which is commonly found in vegetable seed oils. This is the parent fatty acid of n-6 series PUFA, which can be converted in vivo to C20 and C22 n-6 long chain (LC) PUFA. α‐linolenic acid (ALA; 18:3n-3) is less abundant than LA and is another essential fatty acid; ALA is also present in some vegetable oils such as perilla, flaxseed, canola, soybean and walnut oils, and is the precursor of C20 and C22 n-3 LC PUFA. Sterols are widely distributed in animal tissue and plants, with cholesterol being the major sterol in animal tissue and β-sitosterol, campesterol and stigmasterol being the main sterols in plants. It has long been recognized that an increased dietary intake of saturated fat and (to a lesser extent) cholesterol, raises plasma/serum total and low-density lipoprotein (LDL)-cholesterol, and PUFA decreases these levels. Results from recent studies have shown that plasma/serum levels of lipids and lipoprotein lipids can also be decreased by plant sterols (phytosterols) and diacylglycerol (DAG). Conjugated linoleic acid (CLA, cis-9,trans-11−18:2) has been reported to have anticancer and antidiabetic activities. Fat as the DAG form has also been reported to have anti-obesity effects. Omega-3 PUFA have a beneficial effect on increased heart rate variability, decreased risk of stroke, reduction of both systolic and diastolic blood pressure and may be effective in managing depression in adults. Gamma-linolenic acid (GLA) and phytosterols have an anti-inflammatory activity. The GLA, when combined with docosahexaenoic acid (DHA), have been reported to have a beneficial effect in hyperactive children. These data show that various lipids are powerful bioactive compounds.

The first and last stages of filmmaking production and projection remain relatively unchanged, but computerization (through digitalization) has radically transformed film and sound editing. The aim here is to examine some of the effects of this transformation on postproduction employment. The experiences of twenty Victorian postproduction workers, interviewed in 2001, provide the data presented here. The interviewees were divided into groups to reflect their life stage and time working in postproduction.

Many microbial peptide secondary metabolites possess important medicinal properties, of which the immunosuppressant cyclosporin A is an example. The enormous structural and functional diversity of these low-molecular weight peptides is attributable to their mode of biosynthesis. Peptide secondary metabolites are assembled non-ribosomally by multi-functional enzymes, termed non-ribosomal peptide synthetases. These systems consist of a multi-modular arrangement of the functional domains responsible for the catalysis of the partial reactions of peptide assembly. The extensive homology shared among NRPS systems allows for the generalisation of the knowledge garnered from studies of systems of diverse origins. In this review we shall focus the contemporary knowledge of non-ribosomal peptide biosynthesis on the structure and function of the cyclosporin biosynthetic system, with some emphasis on the re-direction of the biosynthetic potential of this system by combinatorial approaches.

Aims & Rationale/Objectives
To locate, analyse and make accessible innovative models of health training and service delivery that have been developed in response to a shortage of skills.

Methods
Drawing on a synthesis of Australian and international literature on innovative and effective models for addressing health skill shortages, 50 models were selected for further study. Models were also identified from nominations by key health sector stakeholders. Selected models represent diversity in terms of the nature of skill shortage addressed, barriers overcome in developing the model, health care specialisations, and customer groups.

Principal Findings
Rural and remote areas have become home to a set of innovative service delivery models. Models identified encompass local, regional and state/national responses. Local responses are usually single health service-training provider partnerships. Regional responses, the most numerous, tend to have a specific focus, such as training young people. A small number of holistic state or national responses, eg the skills ecosystem approach, address multiple barriers to health service provision. Typical barriers include unwillingness to risk-take, stakeholder differences, and entrenched workplace cultures. Enhancers include stakeholder commitment, community acceptance, and cultural fit.

Discussion
Of particular interest is increasing numbers of therapy assistants to help address shortages of allied health professionals, and work to formalise their training, and develop standards of practice and policy. Other models likely to help address skill shortage amongst VET health workers focus on recruiting, supporting and training employees from a range of disadvantaged target groups, and on providing career paths with opportunities for staff to expand their skills. Such models are underpinned by nationally recognised qualifications, but each solution is targeted to a particular context in terms of the potential workforce and local need.

Educating students for the future involves providing them with skills to cope with technological change. Schools and teachers have been adapting their practices in mathematics and science to incorporate information and communication technology (ICT) as a routine aspect of learning. However, recent research indicates that not all students have equal access to the technologies they need. A number of reasons are investigated: the location of the schools (regional and rural settings), the capabilities of the teachers and access by staff and students to high quality resources. This paper presents the findings of this research.

This thesis explores the construction of technological expertise amongst a heterogenous group of New Zealand teenagers, specifically in regard to their home computer use, which for many of them is their primary site of leisure. This thesis explores the field in which these teenagers are positioned, and explains the practice constituting that field. In this field, the trajectories towards expertise are explained including the time, experimentation, and pleasure evident in their praxis. The qualitative study involved observations and interviews with eight teenagers aged 13 – 17. Five boys and three girls participated and each attended one of various secondary schools located within a provincial city in New Zealand. All of the participants considered themselves to be technological experts, and their peers and/or their family supported this comprehension. Drawing on Pierre Bourdieu’s socio-cultural theories, the capital (cultural, economic, social) and habitus of the teenagers are described (habitus being what makes them who they are, and continues to define who they are in the future). Chapter five centres on explaining the field the teenagers have positioned themselves in, namely the field of out-of-school leisure and home computer use. It also explores the construction and performance of technological expertise within the field. Chapter six examines traditional views of schooling and expertise, and contrasts these views with what the teenagers think about their learning and expertise. This gap is specifically explained with regard to differences between the concepts and value of learning, expertise, and technology, and how they are recognised and valued differently between generations. Chapter seven explores the praxis that the participants exhibit, which is arguably misrecognized by those whose interests are in the established order (e.g. institutional, societal structures). The field they are placed in is arguably part of the broader field of education, yet the findings suggest their capital is misrecognized by digital newcomers, and therefore not legitimated. This thesis concludes that the gap between teenager and adult understandings of expertise is exacerbated in the digital world in which the teenagers position themselves. Their schooling is mainly positioned in the print culture of previous generations and consequently, in the lives of these teenagers, schooling has had little influence on the development of their technological expertise. Additionally, gender has had little impact in their development of expertise; therefore stereotypical notions of female underachievement as computer experts are contested.

This study explores the notion of contestation in environmental education. Contestation is a process in which self-interested individuals and groups in a social organisation cooperate, compete and negotiate in a complex interaction aimed at solving social problems. A "framework for critique" is developed, comprising technicist, liberal
