Doubles or nothing : the problem of binding truth to being in the work of Alain Badiou

In this article, I discuss how things go with the "Nothing" in the work of Alain Badiou, a topic which is evidently central to his thought, and which has received a great deal of attention in the commentary to date. As this problem is inaccessible outside of Badiou’s deployment of mathematics, I will suggest how accounts of Badiou’s work remain flawed insofar as they evade his mathematical demonstrations, and I attempt to clarify how mathematics operates in his system. I then examine the consequences that such a use of mathematics has for Badiou’s doctrine of the nothing. I conclude with a discussion of some of the difficulties that the nothing continues to pose to Badiou, which have not (yet) been satisfactorily resolved. These difficulties devolve from the problematic of the incessantly doubling void.

A knowledge management approach to user support

This paper considers the problem of computer user support and workplace learning in general. Theoretically our work is influenced by ideas on knowledge management, expertise networks and communities of practice. Our approach seeks to tap into the powerful and situated learning potential of the collaborative support provided by colleagues. We consider that such support could be enhanced through the use of a collaborative support system. We outline our investigations into design issues, a generic model and various experiments related to the development of such a system. In particular, we emphasise the value of recorded demonstrations for representing computer-related practice. We present a number of design conclusions derived from our experiences, and warn that whereas active user participation is the essential ingredient in a support system it is perhaps the most difficult thing to achieve.

A hybrid FIA/HPLC system incorporating monolithic column chromatography

We have combined the generation of solvent gradients using milliGAT pumps, chromatographic separations with monolithic columns and chemiluminescence detection in an instrument manifold that approaches the automation and separation efficiency of HPLC, whilst maintaining the positive attributes of flow injection analysis (FIA), such as manifold versatility, speed of analysis and portability. As preliminary demonstrations of this hybrid FIA/HPLC system, we have determined six opiate alkaloids (morphine, pseudomorphine, codeine, oripavine, ethylmorphine and thebaine) and four biogenic amines (vanilmandelic acid, serotonin, 5-hydroxyindole-3-acetic acid and homovanillic acid) in human urine, using tris(2,2′-bipyridyl)ruthenium(III) and acidic potassium permanganate chemiluminescence detection.

Supermarkets as a setting to promote health eating : some lessons learnt in Victoria

Issue addressed: Supermarkets are a potential setting in which to deliver nutrition promotion to the community. A pilot project was able to examine the requirements for health authorities to form partnerships with other sectors and opportunities and limitations of using industry- based communication strategies to promote healthy eating messages. Methods: Pre-intervention interviews helped determine communication strategies. Post-intervention interviews were used to assess content and appropriateness of nutrition resources, collaboration between key participants, satisfaction with training and barriers/promoters to implementation. An intercept survey with consumers measured the impact of the intervention. Results: The survey of more than 1,120 women indicated only limited success. 12% of respondents from the intervention supermarkets had watched demonstrations and 20% had noticed the recipe leaflets, with only 5% able to name the promotion. Supermarket owners, representatives from participating food companies and demonstrators were supportive of the concept and content used in the promotion and qualitative analysis provides indicators for similar promotions. Conclusions: Health authorities considering 'partnerships' with the food/supermarket industry should recognise the diversity of roles and responsibilities of the organisations involved in the supply of food through the retail market and allow for long term planning when working with them. Head office of the supermarket group has a key coordinating role, however, individual supermarkets will be driven by financial returns. So what?: The recognition and trust in the name of health authorities by consumers means that organisations value an association with them.

Using Excel to generate empirical sampling distributions

Teachers in many introductory statistics courses demonstrate the Central Limit Theorem by using a computer to draw a large number of random samples of size n from a population distribution and plot the resulting empirical sampling distribution of the sample mean. There are
many computer applications that can be used for this (see, for example, the Rice Virtual Lab in Statistics: http://www.ruf.rice.edu/~lane/rvls.html). The effectiveness of such demonstrations has been questioned (see delMas et al (1999))) but in the work presented in this paper we do not rely on sampling distributions to convey or teach statistical concepts; only that the sampling distribution is independent of the distribution of the population, provided the sample size is sufficiently large.

We describe a lesson that starts out with a demonstration of the CTL, but sample from a (finite) population where actual census data is provided; doing this may help students more easily relate to the concepts – they can see the original data as a column of numbers and if the samples are shown they can also see random samples being taken. We continue with this theme of sampling from census data to teach the basic ideas of inference. We end up with standard resampling/bootstrap procedures.

We also demonstrate how Excel can provide a tool for developing a learning objects to support the program; a workbook called Sampling.xls is available from www.deakin.edu.au/~rodneyc/PS > Sampling.xls.

Dual sector education : Tafe and higher education collaborate in construction management

Curriculum collaboration between TAFE (vocational college) and universities in Australia has had a chequered history. Attempts to collaborate on curriculum development and delivery have mostly been at the margins of articulation and educational pathways. This study examines a pilot project in dual sector construction management education conducted at RMIT University over a two year period. The study demonstrates the challenges with mutual curriculum development between TAFE and higher education in Australia, and demonstrates the methods utilised to overcome these challenges. The results of the projects reveal that the benefits to students in hands-on experiences, theoretical knowledge gained and practical demonstrations were invaluable and worthy of ongoing research and development. The paper also raises critical questions about flexibility and mobility in educational institutions in Australia.

The best of both worlds – how vocational education can enhance university studies in construction management

Australian post-compulsory vocational or technical education and higher education (university) has traditionally been delivered separately. Attempts to collaborate on curriculum development and delivery have mostly been at the margins of articulation and educational pathways. This study examines a pilot project in construction management education conducted at RMIT University over a two-year period. The study demonstrates the challenges with mutual curriculum development between vocational and higher education in Australia and demonstrates the methods utilised to overcome these challenges. The results of the project reveal that the benefits to students in hands-on experiences, theoretical knowledge gained and practical demonstrations were invaluable and worthy of ongoing research and development. The article also raises critical questions about flexibility and mobility in educational institutions in Australia.

Iraq and the Arab revolutions : protesting the failure to democratise governance

As the Arab Revolutions swept across the Middle East and North Africa in late 2010 and into 2011, Iraqis were confronted with the failures of their own democracy to deliver on the many promises made to them since 2003. This led to weeks of scattered protests across Iraq, culminating in the “Day of Rage” (February 25, 2011) in which thousands of protestors took to the streets in at least 17 separate demonstrations across the country following Friday prayers. On the surface, these protests shared much in common with others across the region: the use of Facebook and other social media to promote the protests, and the focus on corruption, unemployment and poor public infrastructure. Also similar was the reaction of key Iraqi political figures such as Maliki and Barzani who met Iraqi protests with a mixture of brutal suppression and modest political and economic concessions. However, as this paper will demonstrate, upon closer inspection the Iraqi protests are in fact very different to others across the MENA and are therefore among the most significant for the future of democracy in the region. The Iraqi people were not protesting against an autocratic regime or an entrenched monarchy that had held power for decades, but a relatively new – and supposedly ‘democratic’ - political elite who had been brought to power in the wake of the US invasion. Indeed, while protestors across the region called for more democracy in the form of a written constitution, free and fair elections, a robust media sphere and the rule of law, Iraqis were protesting against the failures of the Iraqi government to democratise such mechanisms of governance (all of which they more or less have). They felt routinely disenfranchised by a state that has manipulated the very institutions and discourses of democracy to retain, rather than diffuse, power.

The streets of Iraq: protests and democracy after Saddam

This chapter seeks to document and examine the Iraqi people’s exercise of their right to protest and the influence these protests have had on the political landscape of the post-Saddam era. Since 2003, the Iraqi people have frequently taken to the streets en masse, to air their concerns about everything – from the ongoing US-led occupation to the government’s failure to provide basic security and infrastructure and to the airing of ‘indecent’ programmss on Iraqi television. This paper concludes by arguing that Iraqi citizens who play an active role in their own governance and participate in democratic mechanisms such as elections and mass demonstrations are helping to create a more robust democracy.

Improved manufacturing quality and bonding of laser machined microfluidic systems

Laser micro-machining offers a versatile tool for the rapid manufacturing of polymeric microfluidics systems, with a typical turn-around-time in the order of minutes. However, the chaotic nature of the thermal evaporative ablation process can yield a significant number of defects in the surface of the manufactured microchannels, in the form of residual condensed material. In this work we have investigated the use of solvent evaporation by which to not only laminate bond the laser machined structures but to remove a significant number of the defect formed by the condensation of residual polymer. Results are presented of the surface profiling of the bonded channel structures and demonstrations of the bonding of the microchips to produce autonomous capillary microchannels.
