Floating lives : cultural citizenship and the limits of diaspora

Cultural citizenship may, in the simplest terms, be taken to mean a certain 'fit' or compatibility between the cultural attributes of an individual or group and those of the society in which they live. It is a complex concept, taking in rights, responsibilities and competencies as well as the more intangible issues of identity and belonging which have been the subject of intense debates within cultural studies in the last decade. In the case of diasporic or transnational peoples, it is further complicated by the fact of their multiple and unstable cultural and/or civic allegiances (to home and host nations in the first instance, but frequently also to the cultural space of diaspora itself).

This essay examines recent life stories by Chinese Australians: Clara Law's film Floating Life (1996) and two novellas by Liu Guande and Huangfu Jun, published together in English under the title Bitter Peaches and Plums (1995). Focusing on the diversity of experience evoked by notions of cultural belonging, it argues against the prevalent tendency within diaspora studies to engage in a rhetoric of cultural essentialism. The literatures of diaspora deserve to be read as documents of unique and complex cultural experiences rather than mere illustrations of archetypes

Fixed and floating charges : the latest conflicting law and how to address the gaps

Can book debts be subject to a fixed charge? This question was considered by the House of Lords in National Westminster Bank v. Spectrum Plus Limited [2005] UKHL 41 where the full House was against the idea of a fixed charge on book debts and insisted that only a floating charge had been created. The law in this area is still vague and uncertain in Australia. This paper argues that the financiers and the companies should be given the freedom to decide how they wish to structure their charge documents. The paper sets out to argue that, in respect to the use of book debts as security for a loan, the only way for both the financiers and the companies to do business is to create a sustained workable fixed charge or even multiple fixed and floating charge on book debts. The author explains how this could be possible and how the proposed model would not deny the statutory priority rights of the preferential creditors.

Reductions in nutrient discharge from aquaculture through recycling of water utilising floating media and activated carbon filtration

Nutrient discharge into coastal areas, such as the Great Barrier Reef can result in the degradation of coastal ecosystems. For example, excess nitrogen and phosphorus can damage corals through inducing algal bloom and subsequent shading. Excessive phosphorus can further weaken coral skeletons making them susceptible to damage. Land based industries such as aquaculture can contribute to such problems. This study set out to develop a system whereby water from aquaculture can be constantly reused resulting in minimized waste discharge. A three-stage filtration system utilizing floating media and activated carbon was designed to harness bacterial processes that could reduce both particulate and dissolved compounds to the extent whereby approximately 100% reuse of the wastewater became possible. This involved efficient and effective particulate and biological removal mechanisms in both aerobic and anaerobic zones of the filtration system. This design reduced dissolved nitrogen levels by up to 70% and maintained low phosphorus levels, which allowed the reuse of water for the successful culture of barramundi with a survival rate of 97% over 25 days. This pilot scale study demonstrated the potential of reusing aquaculture wastewater from the viewpoint of reducing nutrient input into coastal environments. Future research will refine these processes and assess the performance of the system at several commercial scale applications.

Application of floating medium filters for aquaculture wastewater treatment

Filtration is an effective process in removing particles of various nature and sizes that are present in water and wastewater. It has been used as a final clarifying step in water treatment since the19th century. It is becoming increasingly important in the tertiary treatment step of wastewater to produce effluent of superior quality for the purpose of reuse. Filtration is particularly applied when high flow rates of water with relatively low contents of suspended solids have to be treated. In a conventional water or wastewater treatment system, the filters are usually placed after sedimentation units to remove suspended particles, which escape without settling in the sedimentation units. When chemically pretreated and flocculated water is applied to a filter without a prior-solid liquid separation it is called direct filtration.

Mathematical modelling of downflow floating medium filter (DFF) with in-line flocculation arrangement

A laboratory-scale set-up consisting of rapid mixing device and floating medium filter was used to study the use of a downflow floating medium filter (DFF) with an in-line flocculation arrangement as a static flocculator and a prefilter. The semi-empirical mathematical model formulated incorporates flocculation within the filter, particle/floc attachment onto the filter and the detachment of flocs from the medium. The mathematical model for filtration takes into account the expansion of the filter bed. The removal efficiency of DFF and headless development were successfully simulated for different conditions of filtration velocity, filter depth and influent suspended solids (SS). The values of attachment coefficient a(p)β and headless coefficient β1 were found to be independent of filtration velocity, filter depth and influent SS concentration.

The trasition from fixed to floating exchange rate regimes: the case of Brazil

This dissertation evaluates macroeconomic management in Brazil from 1994 to the present, with particular focus on exchange rate policy. It points out that while Brazil's Real Plan succeeded in halting the hyperinflation that had reached more than 2000 percent in 1993, it also caused significant real appreciation of the exchange rate situation that was only made worse by the extremely high interest rates and ensuing bout of severe financial crises in the intemational arena. By the end of 1998, the accumulation of internai and externai imbalances led the authorities to drop foreign exchange controls and allow the currency to float. In spite of some initial scepticism, the flexible rate regime cum inflation target proved to work well. Inflation was kept under control; the current account position improved significantly, real interest rates fell and GDP growth resumed. Thus, while great challenges still lie ahead, the recent successes bestow some optimism on the well functioning of this exchange rate regime. The Brazilian case suggests that successful transition from one foreign exchange system to another, particularly during financial crisis, does not depend only on one variable be it fiscal or monetary. In reality, it depends on whole set of co-ordinated policies aimed at resuming price stability with as little exchange rate and output volatility as possible.
