Analytic prediction of structural stress-strain relations of microstructured metal

Nanostructured and ultra-fine grained metals have higher strength but extremely limited ductility compared to coarse grained metals. However, their ductility can be greatly improved by introducing a specific range of grain sizes in the microstructures. In the paper, multiscale unit cell approach (UCA) is developed and applied to predict the averaged stress-strain relations of the multiscale microstructure metals. The unit cell models are three-phase structured at different scale lengths of 100 nm, 1 μm and 10 μm with different volume fractions and periodic boundary conditions. The contributions of multi-scale microstructures to the macroscopic structural properties of metals are also studied using a analytic approach—two-step mean-field method (TSMF), where three microstructural parameters are introduced and thus mechanical properties such as strength and ductility are presented as a function of these parameters. For verification of these proposed numerical and theoretical algorithms, the structural properties of the pure nickel with three-grain microstructures are studied and the results from FEA and the proposed theory have good agreement.

Corporate social responsibility, new activism and public relations

Purpose – This paper aims to analyse why some contemporary corporate organisations are reluctant to articulate the effect of their market positioning behaviour on the unwilling communities that oppose their activities. It describes the communicative interactions between several large corporate organisations and the grassroots activist groups opposing their activities, in Victoria, Australia.

Design/methodology/approach – Extensive secondary data were collected, including extensive newspaper and radio transcripts from the campaign periods, web site downloads, letters and other campaign documents. The research design applied to the data, a qualitative, interpretative analysis, drawing on key theoretical frameworks.

Findings – The research findings suggest that powerful protest strategies, combined with the right political and social conditions, and a shift in the locus of politics and expertise, bring to light public concerns about the ethics of corporate practices, such as public relations, used egocentrically by organisations, to harmonise their activities in late modern Western society. It finds that no serious overhaul of business ethics can occur until the unity of public relations is critically scrutinised and reformed. It helps define an alternative holistic communicative approach which could be applied more widely to business practice that helps avoid the limitations and relativism of public relations.

Originality/value – The research flags new ways of thinking expressed in the notion of public communication that could lead to creative and unusual coherences vital to deal with the apparent ecological challenges for society in late modernity.

Public relations and the rhetoric of civil society

The intention of this paper is to build on a book by Anne Surma (2005). It takes some of Surma’s ideas probably beyond what was originally intended in order to suggest their logical conclusions for the practice of public relations. Surma argues that writing and reading of every type enables or otherwise facilitates or restricts imagination. Further, this shaping or inflection of the imagination leads to the shaping or the inflection of the type of ‘ethic’ which we are able to hold in our heads about the world which surrounds us. If this is the case then public relations writing, which has the very raison d’etre of influencing thought, must lend itself to important analysis in this regard. This paper presumes the reader has a basic understanding of Charles Saunders Peirce’s notion of semiotics.

Industry differences in the neoliberal transformation of Australian industrial relations

This article argues that our theoretical understanding of neoliberalism and empirical understanding of the transformation of industrial relations in Australia since the early 1990s can be improved by disaggregating analysis from national to industry level, and by focusing on the dual neoliberal objectives of decollectivisation and individualisation.

Ambivalent relations : the 'tricky footwork' of parental involvement in school communities

Parental involvement in schools, generally seen to be a good thing, is now closely linked through policy to the educational achievement of their children. In this Victorian case study, teacher and parent responses to policies advocating parental involvement are examined. It explores the intersections of gender and class in the context of changing home/school relationships characterised by policies and processes of institutionalisation, familialisation and individualisation that are shaping parental involvement. It suggests that the current discursive construction of parent/school relationships around partnerships for student learning fail to recognise the complexity of parent/teacher relations and its gendered nature. Feminist critical policy analysis framed by the sociology of the family inform our understandings of the ways changing discourses and practices currently are informing parental involvement in a culturally and socio-economically diverse school.

Language, power and ruling relations in vocational education and training

This thesis uses institutional ethnography to explore the text-based regulatory framework of the Australian Vocational Education and Training (VET) sector. Training Packages are national competency standards used to assess local workplace practice. The Australian Quality Training Framework (AQTF) is a national compliance framework used to audit local learning and assessment practice. These texts operate in a ‘symbiotic relationship’ to achieve a policy goal of national consistency. The researcher explicates the social relations of VET starting from her disquiet as a practitioner. The thesis argues that Training Packages and the AQTF socially organise the content and delivery of local learning and assessment activities. VET practitioners struggle to use these texts to support good practice, and their hidden work maintains an unstable VET system. Yet the extralocal mode of ruling offers no room to challenge VET policy. The thesis explicates three themes. Interview data is used to explore the contrast between the institutional language of Training Packages and the vernacular of workplaces in which these texts are activated. Many practitioners and participants simply do not understand Training Package competency standards. Using these texts to judge employee performance shifts the policing of workplace practice from local sites to external VET authorities. A second theme emerges as the analysis explores why VET practitioners use this excluding language in their work with participants. Interview data reveals that local training organisations achieve different readings as they engage with ruling VET texts. Some organisations use the national texts as broad frameworks, allowing practitioners to create spaces for meaningful learning. Other organisations adopt a narrow and rule-bound reading of national texts, displacing practitioners’ authority over their own practice. A third theme is explored through examination of a sequence of VET texts. The review and redevelopment of the mandatory qualifications for VET practitioners identified the language of the competency standards as a significant accessibility issue. These concerns were reshaped and subsumed in an official response that established the use of this language as a compulsory assessable requirement and a language and literacy benchmark. The thesis presents a new understanding of VET as a regulatory framework established through multiple levels of ruling texts that connect local sites to national government agendas. While some individual practitioners are able to navigate through this system, there is an urgent need for practitioners as a profession to challenge national hegemony.
