States or state sequences in neural network models are made to represent concepts from applications. This paper motivates, introduces and discusses a formalism for denoting such representations; a representation for representations. The formalism is illustrated by using it to discuss the representation of variable binding and inference abstractly, and then to present four specific representations. One of these is an apparently novel hybrid of phasic and tensor-product representations which retains the desirable properties of each.

Recent years have seen advances in neuroimaging to such an extent that neuroscientists are able to directly study the frequency, location, and timing of neuronal activity to an unprecedented degree. However, marketing science has remained largely unaware of such advances and their huge potential. In fact, the application of neuroimaging to market research - what has come to be called 'neuromarketing' - has caused considerable controversy within neuroscience circles in recent times. This paper is an attempt to widen the scope of neuromarketing beyond commercial brand and consumer behaviour applications, to include a wider conceptualisation of marketing science. Drawing from general neuroscience and neuroeconomics, neuromarketing as a field of study is defined, and some future research directions are suggested. © 2006 Elsevier B.V. All rights reserved.

The main aim of this article is to shed some light on the way in which actor network theory (ANT) might contribute to case research in accounting. The paper will seek to explain some of the theoretical suppositions which are commonly associated with ANT and which have so far made little impact on the accounting literature. At the same time the accounting literature has shown a particular reluctance to engage with the central concept of ANT which Lee and Hassard characterise as the desire to bring together the "human and non-human, social and technical factors in the same analytical view". The article also features a discussion of a research project which used an approach giving emphasis to both humans and objects in order to understand how ``facts'' have come to be settled as they are. In taking such views into the research it is hoped to provide insight into both the detail of accounting as it is practised within organisations and the manner in which human actors and objects of technology may combine to constitute networks within organisations.

In recent years, technologically advanced methodologies such as Translog have gained a lot of ground in translation process research. However, in this paper it will be argued that quantitative research methods can be supplemented by ethnographic qualitative ones so as to enhance our understanding of what underlies the translation process. Although translation studies scholars have sometimes applied an ethnographic approach to the study of translation, this paper offers a different perspective and considers the potential of ethnographic research methods for tapping cognitive and behavioural aspects of the translation process. A number of ethnographic principles are discussed and it is argued that process researchers aiming to understand translators’ perspectives and intentions, how these shape their behaviours, as well as how translators reflect on the situations they face and how they see themselves, would undoubtedly benefit from adopting an ethnographic framework for their studies on translation processes.

This edition of Polymer Degradation and Stability comprises selected papers presented at the 27th Polymer Degradation Discussion Group (PDDG) Conference, affiliated to the Macromolecular Group of the Royal Society of Chemistry, held at Aston University, Birmingham (UK), September 2007, in honour of Professor Norman Billingham for lifelong career in Polymer Science. Norman Billingham was one of the main founders of the PDDG meetings which have been held annually at different venues in the UK since 1976, and biennially since 1998. The PDDG meetings are forums for scientific developments and open discussion of all aspects of polymer degradation and stabilisation and have always provided younger researchers a platform for presenting and discussing their work in the field. This 27th PDDG meeting, chaired by Sahar Al-Malaika (Aston University), was dedicated to Norman Billingham, the Guest of Honour, in recognition for his distinguished contributions to Polymer Science particularly in the area of polymer degradation and stabilisation. The meeting was attended by 65 delegates from 15 countries in Europe, USA and Australia, many of whom have worked and collaborated with Norman at some points of their career. The guest editors of this issue wish to add their Congratulations to Norman Billingham for his outstanding contributions and achievements in the field of polymer degradation and stabilisation and to wish him very happy years ahead. We wish also to express our gratitude to Elsevier for sponsoring the 27th PDDG event and our appreciation to Professor Norman Billingham in his capacity as the Editor-in-Chief of Polymer Degradation and Stability, for the support and help received during the preparation of this special issue.

The Internet poses a number of threats to the safety of young people. Using numerous examples, this article discusses a wide range of such threats, including: cyberstalking; the 'grooming' of potential victims of sexual abuse; a new 'wish list' scene (where teenagers encourage contact with potential abusers); the creation and distribution of child pornography; and the emergence of services that create child pornography to order. It is suggested that the latter has provided individuals with the ability to inflict sexual abuse on young people from a distance, an act the authors have termed virtual sex tourism. The final section of the article suggests that paedophiles and pornographers have been quick to adopt new technology as a means of concealing their activities. The article concludes by warning of the danger of overestimating or underestimating the threats described.

With the European Commission making global leadership claims in the field of audit regulation, the content of its 2010 Green Paper on ‘Audit Policy: Lessons from the Crisis’ warrants careful scrutiny. Important issues raised in the Green Paper include regulatory oversight, competition in the audit market, the dangers of having very few firms with the capacity to audit global transnational corporations, professional judgement, innovative audit practices and, last but not least, social responsibility. This article analyses the principal perspectives and assumptions underpinning the construction of the Green Paper. The aims are threefold: to enhance understanding of the contemporary regulatory mindset of the European Commission, contribute to policy debate and inspire future research.

Introduction: There is a growing public perception that serious medical error is commonplace and largely tolerated by the medical profession. The Government and medical establishment's response to this perceived epidemic of error has included tighter controls over practising doctors and individual stick-and-carrot reforms of medical practice. Discussion: This paper critically reviews the literature on medical error, professional socialization and medical student education, and suggests that common themes such as uncertainty, necessary fallibility, exclusivity of professional judgement and extensive use of medical networks find their genesis, in part, in aspects of medical education and socialization into medicine. The nature and comparative failure of recent reforms of medical practice and the tension between the individualistic nature of the reforms and the collegiate nature of the medical profession are discussed. Conclusion: A more theoretically informed and longitudinal approach to decreasing medical error might be to address the genesis of medical thinking about error through reforms to the aspects of medical education and professional socialization that help to create and perpetuate the existence of avoidable error, and reinforce medical collusion concerning error. Further changes in the curriculum to emphasize team working, communication skills, evidence-based practice and strategies for managing uncertainty are therefore potentially key components in helping tomorrow's doctors to discuss, cope with and commit fewer medical errors.
