The merits of a research project are commonly framed in terms of perceived benefits with respect to knowledge production, wellbeing, the social good, and so on. Such measures can, however, be at odds with certain types of creative practice, which may be perceived as frivolous, unsettling, or shocking. Moreover, creative practice research methodologies commonly eschew more traditional research conventions. In exploring these tensions, this live performance event (including a DVD component) adapted key dramatic principles developed in Geoffrey Robertson's groundbreaking Hypotheticals. The event was presented for an audience of staff and students at QUT's Creative Industries Faculty in July 2010. It confirmed Dr Angela Romano's contention that: “Part of the ethical clearance process for practice-led researchers will be to find a language to explain the methodology, significance, merit and integrity of their research to people outside their field of practice.” (Angela Romano, QUT Creative Industries) “Part of the ethical clearance process for practice-led researchers will be to find a language to explain the methodology, significance, merit and integrity of their research to people outside their field of practice.”

For many decades correlation and power spectrum have been primary tools for digital signal processing applications in the biomedical area. The information contained in the power spectrum is essentially that of the autocorrelation sequence; which is sufficient for complete statistical descriptions of Gaussian signals of known means. However, there are practical situations where one needs to look beyond autocorrelation of a signal to extract information regarding deviation from Gaussianity and the presence of phase relations. Higher order spectra, also known as polyspectra, are spectral representations of higher order statistics, i.e. moments and cumulants of third order and beyond. HOS (higher order statistics or higher order spectra) can detect deviations from linearity, stationarity or Gaussianity in the signal. Most of the biomedical signals are non-linear, non-stationary and non-Gaussian in nature and therefore it can be more advantageous to analyze them with HOS compared to the use of second order correlations and power spectra. In this paper we have discussed the application of HOS for different bio-signals. HOS methods of analysis are explained using a typical heart rate variability (HRV) signal and applications to other signals are reviewed.

The ability to reproducibly load bioactive molecules into polymeric microspheres is a challenge. Traditional microsphere fabrication methods typically provide inhomogeneous release profiles and suffer from lack of batch to batch reproducibility, hindering their potential to up-scale and their translation to the clinic. This deficit in homogeneity is in part attributed to broad size distributions and variability in the morphology of particles. It is thus desirable to control morphology and size of non-loaded particles in the first instance, in preparation for obtaining desired release profiles of loaded particles in the later stage. This is achieved by identifying the key parameters involved in particle production and understanding how adapting these parameters affects the final characteristics of particles. In this study, electrospraying was presented as a promising technique for generating reproducible particles made of polycaprolactone, a biodegradable, FDA-approved polymer. Narrow size distributions were obtained by the control of electrospraying flow rate and polymer concentration, with average particle sizes ranging from 10 to 20 um. Particles were shown to be spherical with a homogenous embossed texture, determined by the polymer entanglement regime taking place during electrospraying. No toxic residue was detected by this process based on preliminary cell work using DNA quantification assays, validating this method as suitable for further loading of bioactive components.

This chapter presents a new approach to IT ethics education that may be used by teachers in academic institutions, employees responsible for promoting ethics in organisations and individuals wanting to pursue their own professional development. Experiential ethics education emphasises deep learning that prompts a changed experience of ethics. We first consider how this approach complements other ways of engaging in ethics education. We then explore what it means to strive for experiential change and offer a model which may be useful in pursuing IT professional ethics education in this way.

The ethical conduct of professionals has been the focus of increasing scrutiny over the past several decades as members of the public, the media, professional bodies, and legislative authorities have struggled to define ethical behaviour in times of governmental change, increasing internationalisation, globalised communications, threats of terrorism, and the challenges of developments in science and medicine (e.g., Demmke & Bossaert, 2004). National governments and transnational bodies have responded to these concerns about ethics and corruption through measures such as the United Nations Convention Against Corruption (United Nations Office on Drugs and Crime, 2004), Transparency International’s annual corruption index (2010) and Queensland’s Public Sector Ethics Act 1994 (Queensland Parliament 1994). Similarly, academic interest in ethics and its application across a range of domains(e.g., business, health care, social welfare, criminal justice, law, journalism, defence, environment, and media) has also increased. To illustrate, in 1993, a non-partisan, non-profit national umbrella organisation, the Australian Association for Professional and Applied Ethics, was formed following a conference concerned with the teaching of ethics (http://www.arts.unsw.edu.au./aapae/about_aapae/about_aapae.htm), while a recent review of the Excellence in Research for Australian rankings of national and international academic journals revealed that 16 journals related to ethics had received the top ratings of A* or A (Australian Research Council, 2009). In this chapter we examine professional ethics and argue, with specific reference to the context of pre-service teacher education, that Service-learning is one way of enhancing emerging professionals’ understanding of ethics.

This volume breaks new ground by approaching Socially Responsible Investment (SRI) as an explicitly ethical practice in financial markets. The work explains the philosophical and practical shortcomings of ‘long term shareholder value’ and the origins and conceptual structure of SRI, and links its pursuit to both its deeper philosophical foundations and the broader, multi-dimensional global movement towards greater social responsibility in global markets. Interviews with fund managers in the Australian SRI sector generate recommendations for better integrating ethics into SRI practice via ethically informed engagement with invested companies, and an in-depth discussion of the central practical SRI issue of fiduciary responsibility strengthens the case in favour of SRI. The practical and ethical theoretical perspectives are then brought together to sketch out an achievable ideal for SRI worldwide, in which those who are involved in investment and business decisions become part of an ‘ethical chain’ of decision makers linking the ultimate owners of capital with the business executives who frame, advocate and implement business strategies. In between there are investment advisors, fund managers, business analysts and boards. The problem lies in the fact that the ultimate owners are discouraged from considering their own values, or even their own long term interests, whilst the others often look only to short term interests. The solution lies in the latter recognising themselves as links in the ethical chain.

The emergence of strong sovereign states after the Treaty of Westphalia turned two of the most cosmopolitan professions (law and arms) into two of the least cosmopolitan. Sovereign states determined the content of the law within their borders – including which, if any, ecclesiastical law was to be applied; what form of economic regulation was adopted; and what, if any, international law applied. Similarly, states sought to ensure that all military force was at their disposal in national armies. The erosion of sovereignty in a post-Westphalian world may significantly reverse these processes. The erosion of sovereignty is likely to have profound consequences for the legal profession and the ethics of how, and for what ends, it is practised. Lawyers have played a major role in the civilization of sovereign states through the articulation and institutionalisation of key governance values – starting with the rule of law. An increasingly global profession must take on similar tasks. The same could be said of the military. This essay will review the concept of an international rule of law and its relationship to domestic conceptions and outline the task of building the international rule of law and the role that lawyers can and should play in it.

In this chapter I look at the question of design and ethics in a situation where design as a set of related economic practices has been re-positioned as a key identifier for a new kind of ideas-driven industry - the creative industries. Previously marginal to cultural policy in the form of applied arts, in the creative industries agenda design became a privileged meeting place, or indeed broker, for art and industry, economy and commerce. I explore the new kinds of ethical challenges this brings.
