This paper aims to demonstrate the improved functionality of additive manufacturing technology provided by combining multiple processes for the fabrication of packaged electronics.

This research is focused on the improvement in resolution of conductor deposition methods through experimentation with build parameters. Material dispensing with two different low temperature curing isotropic conductive adhesive materials was characterised for their application in printing each of three different conductor designs, traces, z-axis connections and fine pitch flip chip interconnects. Once optimised, demonstrator size can be minimised within the limitations of the chosen processes and materials.

The proposed method of printing z-axis through layer connections was successful with pillars 2 mm in height and 550 µm in width produced. Dispensing characterisation also resulted in tracks 134 µm in width and 38 µm in height allowing surface mount assembly of 0603 components and thin-shrink small outline packaged integrated circuits. Small 149-µm flip chip interconnects deposited at a 457-µm pitch have also been used for packaging silicon bare die.

This paper presents an improved multifunctional additive manufacturing method to produce fully packaged multilayer electronic systems. It discusses the development of new 3D printed, through layer z-axis connections and the use of a single electrically conductive adhesive material to produce all conductors. This facilitates the surface mount assembly of components directly onto these conductors before stereolithography is used to fully package multiple layers of circuitry in a photopolymer.

New Zealand and Australian agri-food industries are being restructured both as a consequence of the extension of neoliberal policy settings and as a result of the increasing influence of the global supermarket sector. In the EU, supermarkets have sought to standardise and harmonise compliance, with their influence being felt well beyond European boundaries. EurepGAP (a European standard for ‘Good Agricultural Practices’) is an example of an emerging ‘audit culture’ where strict adherence to set rules of operation emerges as the basis for accreditation of goods and services. It represents the trend towards private sector standardization and assurance schemes, and provides an example of the growing importance of the supermarket sector in sanctioning the on-ground activities that occur in the production and processing of farm-derived outputs.

This chapter highlights the influence of EurepGAP protocols in the reorganisation of the agri-food industries of New Zealand and Australia. It argues that – for industries such as vegetable and fruit production, where Europe is the final destination – compliance with EurepGAP standards has largely become essential. In this sense, EurepGAP has emerged as the standard among producers who wish to export their products. The chapter concludes with an assessment of EurepGAP as a form of global agri-food governance that demonstrates a strong relationship between new audit cultures and neoliberal forms of trade regulation. In both Australia and New Zealand, some production sectors have rapidly adopted EurepGAP – despite extra costs, reduced choices over crop management and a lingering sense of resentment at the internal imposition of yet another production audit – primarily as a solution to the politics of risk in the context of high levels of exposure to market requirements under neoliberalism. The implications of this for Antipodean farming are considered in detail.

Earnings forecasts provide useful numerical information concerning the expectations of a firm's future prospects and indicate management's ability to anticipate a firm's changing internal structure and external environment. The reasons for studying the accuracy of earnings forecasts is due to the Securities and Exchange Commission's position on financial forecasts and the issuance of a Statement of Position by the AICPA. These statements are important since they, in part, have motivated researchers to the importance of forecasting financial information. Consequently, if the disclosure of earnings forecasts in financial reports is permissable, the improvement of financial forecasts should be one of the primary concerns of the AICPA, the SEC, and numerous other interested groups.

Feminist research acknowledges the centrality of female knowledge and experience. Within this two further strands can be identified: that many feminist researchers place an emphasis on the social construction of meaning, with particular emphasis on the role of language as the primary vehicle of such constructions; and that within the centrality of female knowledge and experience is a feminist analysis of the role of power in determining the form and representation of social knowledge. The latter is an acknowledgement that feminist research is not just an extension of traditional research in non‐sexist ways and areas of relevance to women but that it must entail a critical evaluation of the research process in terms of its ability to illuminate women's experiences. This should comprise three strands — a critique of traditional theories and methods, the development of more appropriate theories and methods for studying the experience of women and the analysis of the role of the researcher within his/her research.
