Automating human thought processes for a UAV forced landing

This paper describes the current status of a program to develop an automated forced landing system for a fixed-wing Unmanned Aerial Vehicle (UAV). This automated system seeks to emulate human pilot thought processes when planning for and conducting an engine-off emergency landing. Firstly, a path planning algorithm that extends Dubins curves to 3D space is presented. This planning element is then combined with a nonlinear guidance and control logic, and simulated test results demonstrate the robustness of this approach to strong winds during a glided descent. The average path deviation errors incurred are comparable to or even better than that of manned, powered aircraft. Secondly, a study into suitable multi-criteria decision making approaches and the problems that confront the decision-maker is presented. From this study, it is believed that decision processes that utilize human expert knowledge and fuzzy logic reasoning are most suited to the problem at hand, and further investigations will be conducted to identify the particular technique/s to be implemented in simulations and field tests. The automated UAV forced landing approach presented in this paper is promising, and will allow the progression of this technology from the development and simulation stages through to a prototype system

Critical Systems Theory: A Political Economy of Language, Thought, and Technology

An emergent form of political economy, facilitated by information and communication technologies (ICTs), is widely propagated as the apotheosis of unmitigated social, economic, and technological progress. Meanwhile, throughout the world, social degradation and economic inequality are increasing logarithmically. Valued categories of thought are, axiomatically, the basic commodities of the “knowledge economy”. Language is its means of exchange. This paper proposes a sociolinguistic method with which to critically engage the hyperbole of the “Information Age”. The method is grounded in a systemic social theory that synthesises aspects of autopoiesis and Marxist political economy. A trade policy statement is analysed to exemplify the sociolinguistically created aberrations that are today most often construed as social and political determinants.

The politics of literacy in David Almond and Dave McKean’s "The Savage" (2008)

Competency in language and literacy are central to contemporary debates about education in Anglophone nations around the world. This paper suggests that such debates are informing not just educational policy but children’s literature itself as can be seen in Almond and McKean’s The Savage. This hybrid text combines prose and graphic narrative and narration in order to tell the story of Blue, a young British boy negotiating his identity in the aftermath of his father's death. While foregrounding a narrative of ideal masculinity, The Savage enacts and privileges a formal and thematic ideal of literacy as index of individual agency and development. Almond and McKean produce a politicised understanding of language and literacy that simultaneously positions The Savage in a textual tradition of socio-culturally disenfranchised youth, and intervenes in that tradition to (perhaps ironically) affirm the very conditions previously critiqued by that very tradition. Where earlier authors such as Barry Hines sought to challenge normative accounts of language and literacy in order to indict educational policy and praxes, Almond and McKean work to naturalise the very logics of education and agency by which their protagonist has been disenfranchised. In doing so, The Savage exemplifies current approaches to education which claim to value social and cultural diversity while imposing national standardised testing predicated on assumptions about the legitimacy of uniform standards and definitions of literacy.

Rock pools of critical thought : finding a place to think through my higher degree and what a PhD was all about

The rock pools, salt pans, cliffs and bluffs, and the banks of the Coorooman and Pumpkin Creeks within Darumbal and Woppaburra Country are used as a backdrop in this paper, which offers an exploration of one woman’s quest to undertake her PhD and develop as an Indigenous scholar. The paper describes this Country and the use of Country to nourish, develop, stimulate and support the intellect. It draws on Australian and international literature to demonstrate the intellectual growth and development of Indigenous scholars. The paper offers a highly personal narrative of intellectual journeying which shows how we can be agents of change and power in our individual lives, even while power is being exercised over us and we are being oppressed and marginalised as Indigenous peoples.

Social network markets and 'public thought'

This paper approaches its topic in a somewhat crabwise manner, but hopefully by that means it may succeed in reaching its objective without being eaten alive. It comprises a critique of a recent internet post called ‘The Shock of Inclusion’ by Clay Shirky (his contribution to The Edge World Question of 2010), in which he claims (among other things) that ‘the average quality of public thought has collapsed.’

Less food for thought : impact of attentional instructions on intrusive thoughts about snack foods

Intrusive thoughts about food may play a role in unhealthy eating behaviours. Food-related thoughts that capture attention can lead to craving and further intrusive thoughts (Kavanagh, Andrade, & May, 2005). We tested whether diverting attention to mental images or bodily sensations would reduce the incidence of intrusive thoughts about snack foods. In two experiments, participants reported their thoughts in response to probes during three 10 min periods. In the Baseline and Post-task period, participants were asked to let their mind wander. In the middle, Experimental, period, participants followed mind wandering (Control), thought diversion, or Thought Suppression instructions. Self-directed or Guided Imagery, Mindfulness-based Body Scanning, and Thought Suppression all reduced the proportion of thoughts about food, compared to Baseline. Following Body Scanning and Thought Suppression, food thoughts returned to Baseline frequencies Post-task, rather than rebounding. There were no effects of the interventions upon craving, although overall, craving and thought frequency were correlated. Thought control tasks may help people to ignore thoughts about food and thereby reduce their temptation to snack.

Understanding nonsense : breathing life into shibboleths and killing critical thought in higher education

In this paper, I focus on the growing "nonsense industry" which is most apparent in the writing typical of business, government departments, and the financial press. This writing, like technical writing, is characterised by heavy reliance on grammatical metaphor. It endows shibboleths - for instance, "globalisation"; "efficiencies"; "competition"; "modernisation"; "consumer sentiment"; "reform"; and so on - with anthropomorphic qualities. These anthropomorphic artefacts of technocratised language are then presented as having immutable powers over people. Thus they become banal public excuses for negligent practices in both business and government.

Malcolm Shepherd Knowles : A History of His Thought

This book traces the evolution of thinking of the American adult educator, Malcolm Knowles, and maps the development of his conceptual framework over the period 1950 to 1995. It constructs an overall narrative history of Knowles’ thought, and shows how andragogy provided him with both a label and a unifying theme for his practical-theoretical framework aimed at producing self-directed lifelong learners. Knowles died in 1997 and left a large legacy of books and journal articles. The book examines the writings that constitute Knowles' principal works. It identifies the major elements of his thought, shows the interrelationships between ideas and indicates the major phases through which his thinking passed. Importantly, the book establishes that Knowles’ theorising was traceable and that he possessed a clear and coherent conceptual framework.

'In the hands of the Receivers': The Politics of Literacy in The Savage by David Almond and Dave McKean

David Almond and Dave McKean's The Savage is a hybrid prose and graphic novel which tells the story of one young man’s maturation through literacy. The protagonist learns to deal with the death of his father and his own 'savage' self by writing a graphic novel. This article reads The Savage in the context of earlier, 'Northern' literacy narrative - particularly Tony Harrison's poem "Them & [uz]" and Barry Hines' Kes — through the discourse of neoliberalism and the notion of the reluctant boy reader. It is suggested that Almond and McKean are influenced by currently dominant ideologies of gender and literacy.

UK pre-pack reforms : pause for thought in Australia?

On 31 March 2011 the UK Government announced new measures to regulate the use of pre-packaged sales in administration. The legislation is not expected until later in 2011, but the announcement heralds a shift in regulatory attitudes towards pre-packs in the UK which should give all local pre-pack advocates pause for thought when considering the merits of embracing the procedure in Australia. In the Jan-March 2011 edition of the Australian Insolvency Journal, an interesting article by Nicholas Crouch and Shabnam Amirbeaggi extolled the virtues of pre-packs and called for “legislative reform to embrace pre-packs” in Australia. By way of reply (and in a spirit of constructive debate) this article respectfully contends that while pre-packs certainly have their place in preserving business value in certain circumstances, Australia should be careful not to sleepwalk into adopting a procedure which legitimises phoenixing at the expense of creditor confidence and participation in our insolvency regime.
