Within many Anglophone nation states there is significant debate about
the future of public education and its ongoing capacity to provide quality
education. The new knowledge economy not only challenges the position
of educators as the primary producers, disseminators and authorizers of
what is valued knowledge, but also requires them to prepare students for
new ways of working with that knowledge. In the service economies of
post-industrial Western nations, 'knowledge work' is critical to national
productivity and international competitiveness. At the same time, the
globalization logic suggests that the nation state is under threat, and therefore its role as provider of universal services such as education is also threatened.

How to provide cost-effective strategies for Software Testing has been one of the research focuses in Software Engineering for a long time. Many researchers in Software Engineering have addressed the effectiveness and quality metric of Software Testing, and many interesting results have been obtained. However, one issue of paramount importance in software testing – the intrinsic imprecise and uncertain relationships within testing metrics – is left unaddressed. To this end, a new quality and effectiveness measurement based on fuzzy logic is proposed. The software quality features and analogy-based reasoning are discussed, which can deal with quality and effectiveness consistency between different test projects. Experimental results are also provided to verify the proposed measurement.

How to provide cost-effective strategies for Software Testing has been one of the research focuses in Software Engineering for a long time. Many researchers in Software Engineering have addressed the effectiveness and quality metric of Software Testing, and many interesting results have been obtained. However, one issue of paramount importance in software testing — the intrinsic imprecise and uncertain relationships within testing metrics — is left unaddressed. To this end, a new quality and effectiveness measurement based on fuzzy logic is proposed. Related issues like the software quality features and fuzzy reasoning for test project similarity measurement are discussed, which can deal with quality and effectiveness consistency between different test projects. Experiments were conducted to verify the proposed measurement using real data from actual software testing projects. Experimental results show that the proposed fuzzy logic based metrics is effective and efficient to measure and evaluate the quality and effectiveness of test projects.

Headteacher workloads are often in the news. Long hours, punitive audit regimes and excessive amounts of paperwork take their toll on many, including John Illingworth, former National Union of Teachers (UK) President, and ex primary headteacher. In this paper, I investigate a UK BBC Radio 4 human interest interview conducted with Illingworth by the usually acerbic John Humphrys. Mobilising Bourdieu’s notion of field, I examine the interview and argue that the analysis suggests that the media game of market share and the doxa of the fourth estate might work to delimit the capacity of such interviews to speak truth to policy power.

One of the major challenges in healthcare wireless body area network (WBAN) applications is to control congestion. Unpredictable traffic load, many-to-one communication nature and limited bandwidth occupancy are among major reasons that can cause congestion in such applications. Congestion has negative impacts on the overall network performance such as packet losses, increasing end-to-end delay and wasting energy consumption due to a large number of retransmissions. In life-critical applications, any delay in transmitting vital signals may lead to death of a patient. Therefore, in order to enhance the network quality of service (QoS), developing a solution for congestion estimation and control is imperative. In this paper, we propose a new congestion detection and control protocol for remote monitoring of patients health status using WBANs. The proposed system is able to detect congestion by considering local information such as buffer capacity and node rate. In case of congestion, the proposed system differentiates between vital signals and assigns priorities to them based on their level of importance. As a result, the proposed approach provides a better quality of service for transmitting highly important vital signs.

The techniques applied in chronic condition self-management programmes (CCSM) to support patients with chronic conditions are basic counselling and communication strategies that would benefit people at all stages of life and wellness. The question being explored here is why, as a society, we wait until people develop essentially preventable chronic conditions before helping them to develop the life skills they need to manage their lives and their human interactions better rather than working to avoid or prevent many chronic conditions that develop as a result of people lacking such skills? If we were to teach coping and managing skills to everyone in a supportive and structured way, using the peer-led teaching and learning strategies and basic counselling and education processes that have been shown to be successful for other older groups with chronic illness, the overall population impact would be more significant. Therefore why wait until people have chronic conditions before empowering them with basic life management techniques? Do people need to be sick before they can be motivated to live more effective lives? Is sickness the main stimulus for triggering health-related behaviour change or can other factors in people’s lives serve to inform and motivate lifestyle change?

Computerized clinical guidelines can provide significant benefits in terms of health outcomes and costs, however, their effective computer implementation presents significant problems. Vagueness and ambiguity inherent in natural language (textual) clinical guidelines makes them problematic for formulating automated alerts or advice. Fuzzy logic allows us to formalize the treatment of vagueness in a decision support architecture. In care plan on-line (CPOL), an intranet-based chronic disease care planning system for general practitioners (GPs) in use in South Australia, we formally treat fuzziness in interpretation of quantitative data, formulation of recommendations and unequal importance of clinical indicators. We use expert judgment on cases, as well as direct estimates by experts, to optimize aggregation operators and treat heterogeneous combinations of conjunction and disjunction that are present in the natural language decision rules formulated by specialist teams.

Fuzzy logic provides a mathematical formalism for a unified treatment of vagueness and imprecision that are ever present in decision support and expert systems in many areas. The choice of aggregation operators is crucial to the behavior of the system that is intended to mimic human decision making. This paper discusses how aggregation operators can be selected and adjusted to fit empirical data—a series of test cases. Both parametric and nonparametric regression are considered and compared. A practical application of the proposed methods to electronic implementation of clinical guidelines is presented

The Victorian Parliament has recently introduced a Bill which implements home detention as a sentencing option. Home detention is an intuitively appealing reform. The logic behind the proposal seems obvious. Prisons are expensive to run. There are too many offenders in prison. So let's take the cost out of prison by turning the homes of offenders into prisons: classic, user-pays, cost-shifting economics. The level of superficial appeal of the argument in favour of home detention is matched only by the depth of the fallacies underpinning some of the fundamental premises. The most basic of which is the assumption that offenders who are candidates for the new sanction should be in detention (of any kind) in the first place. Further, the narrow objective of reducing imprisonment is misguided. It should not be elevated to a cardinal sentencing objective?otherwise total success could be achieved by simply opening the prison gates. There are also other concerns about the appropriateness of home detention. The degree of pain it inflicts in many cases is questionable and it may also violate the principle that punishment should not be inflicted on the innocent. After examining the arguments for and against home detention, this article suggests the approach that should be adopted to achieve enlightened and meaningful sentencing reform.

The recent High Court decision in Macleod v R establishes that a director and sole shareholder may be convicted of fraudulently applying a company's property even though the person has consented to the personal use of the company's property. It is contended that while this decision is consistent with the weight of precedent, it is wrong in principle. The decision implies that corporations are not only separate legal entities, but that they are highly virtuous legal entities -- incapable of being imbued with the dishonest intentions and activities of the individuals controlling the company.

Over 120 years ago Sir James Burns founded an organisation that is today, the international business group of Burns Philp and Company Ltd. The Group is widely known as a leading producer of yeast products and manufacturer of other bakery ingredients. Its ability to adapt to the ever-changing demands of business is widely recognised. During the late 1980’s however, after the group expanded into the herbs and spices industry its financial state deteriorated. Yet, arguably the Group had entered a market that complimented its then existing core-activities. This paper examines circumstances surrounding that venture into herbs and spices. It argues that the Group’s financial predicament, at that time, was exacerbated by the use of conventional accounting procedures. It illustrates that up-to-date market related financial details, in lieu of accounting book constructs, more aptly assist directors, managers, all stakeholders to conduct business and make informed economic decisions. This paper suggests that it is an entity’s current financial state of affairs, with regard to tangible market referents, that enables a firm’s strategic progress and facilitates proactive management; and in turn, assists in the sustainable development of business throughout the world.

A vexed issue for many artistic researchers is related to the need for the artist/researcher to write about his or her own work in the research report or exegesis. In the creative arts, the outcomes that emerge from an alternative logic of practice are not easily quantifiable and it can be difficult to articulate conclusions objectively given the emotional and ideological investments and the intrinsically subjective dimension of the artistic process. How then, might the artist as researcher avoid on the one hand, what has been referred to as 'auto-connoisseurship', the undertaking of a thinly veiled labour of valorising what has been achieved in the creative work, or alternatively producing a research report that is mere description or history?

In this paper I suggest that a way of overcoming such a dilemma is for creative arts researchers to shift the critical focus away from the notion of the work as product, to an understanding of both studio enquiry and its outcomes as process. I’d like to draw on Michel Foucault’s essay ‘What is An Author ‘ to explore how we might move away from art criticism to the notion of a critical discourse of practice-led enquiry that involves viewing the artist as a researcher, and the artist/critic as a scholar who comments on the value of the artistic process as the production of knowledge.

Foucault’s essay provides artistic researchers with a template for more objective and distanced discourse on the practice-led research process and its writing. It allows researchers to locate themselves within contexts of theory and practice and provides an analytical framework though which researchers might locate themselves and their work within the broader social arena and field of research, As I will show with reference to the work of Donna Haraway and a number of commentaries on Pablo Picasso’s Demioselles d’Avignon, an application of Foucault’s ideas need not negate those subjective and situated aspects of practice as research.

The application of a 'global' model, in practice usually British or American, and generalised sociological concepts to a particular sport and its social and cultural context is not always appropriate. In Australian academia, the custom is particularly appealing, due to the Australian colonial 'cultural cringe', the pattern of automatic deference to overseas (termed 'international') knowledge. This article argues that 'Fresh Prince of Coloma! Dome: Indigenous Logic in the AFL' (Football Studies, 8(1), 2005) inappropriately applies American sociological, and American football, logic to the indigenous Australian game Australian football, which differs in character both as a game and in its social, cultural and political context. The three researchers do not take account of the factors of height and weight in Australian football, and the average size of Aboriginal players, and of the relationship between speed and strength in the game as strategies and tactics change. Both omissions constitute fundamental flaws. American football and sports sociology's ideas of 'central position theory', with a suggestion of underlying racism, is of limited relevance to Australian football. It is also possible that the American sitcom, Fresh Prince of Bel Air, was neither a helpful muse nor a suitable metaphor for research into this subj ect. In Australian football, a game in which few 'central positions' are crucial and in which 'leadership positions' can be found in many parts of the ground, including the half-back flank and the wing, neither size nor position are the only major determinants of significance in the team.
