Banking regulation and market forces in Australia

The purpose of this paper is to use Kane's notion of the regulatory dialectic to analyse the changing nature of bank regulation in Australia. Throughout Australia's economic history, economic regulation of the Australian banking system has not been static but has responded to changes in technology, market forces, and the behaviour of regulated institutions. From this analysis, some inferences about general banking principles and policy can be made.

Convergence in the gender wage gap in Australia over the 1980s: identifying the role of counteracting forces via the Juhn, Murphy and Pierce Decomposition

The paper utilises the Juhn Murphy and Pierce (1991) decomposition to shed light on the pattern of slow male-female wage convergence in Australia over the 1980s. The analysis allows one to distinguish between the role of wage structure and genderspecific effects. The central question addressed is whether rising wage inequality counteracted the forces of increased female investment in labour market skills, i.e. education and experience. The conclusion is that in contrast to the US and the UK, Australian women do not appear to have been swimming against a tide of adverse wage structure changes.

Artificial formation forces for stable aggregation of multi-agent system

This paper introduces, a robust and stable algorithm based on artificial formation forces, for multi-agent system (MAS) aggregation in 2D space. The MAS model with artificial forces; consists of inter-member collision avoidance element, formation generation element and a velocity based damping element; is analysed for stability and convergence. Computer simulations are used to illustrate stability and convergence, and to demonstrate effectiveness of the algorithm.

Enslaved by market forces

The backlash against globalisation appears to have some sections of our business community very worried.

The impact of external forces on cartel network dynamics : Direct research in the diamond industry

This paper describes the impact of external environmental forces on cartel networks. Using a case research approach, this report examines two leading business networks within one industry, over time. The results suggest that (a) bargaining power of intermediaries increases with the advent of new and powerful actors, (b) process activities that cartels previously controlled are being outsourced to new actors sometimes based in developing countries, (c) other actors are acquiring resources once dominated by a cartel, (d) external forces triggered by the illegal diamond trade, such as international regulatory constraints, no longer favour cartels like De Beers, and (e) over time, these and additional environment factors are forcing actors like De Beers who perform rigid process activities to become more flexible. For example,forces are moving cartels which relied previously on hand-picked intermediaries in highly controlled networks to market their products to adopt a flexible market-focused expansion of operations in retail contexts.

Combining the forces of science and conservation to turn around the fortunes of shorebirds

At the start of the 21st century the majority of migratory wader (shorebird) populations are faced with serious threats. This commonly results from the continuous destruction of wetlands, their key habitat. Healthy wetlands are highly biodiverse and extremely vulnerable, and as functioning ecosystems particularly important for us humans for a sustained livelihood (artisanal fisheries, small-scale farming) and our well-being (effective water filtering and cleaning systems). In many parts of the world, wetlands have been seen as wastelands, or even as a source of threat (malaria). Many freshwater wetlands have been drained for agricultural use and mudflats have been reclaimed for settlement and urbanization. Wetlands are continuously squeezed by economic development and increasingly used for recreational activities, and their resources are, in general, notoriously overexploited.

Direct measurement of surface forces due to charging of solids immersed in a nonpolar liquid

Direct measurements of a long-range force between charged solid surfaces in a nonpolar liquid are presented for the first time. Measurements were made between mica surfaces in solutions of the anionic surfactant sodium di-2-ethylhexylsulfosuccinate (AOT) at millimolar concentrations in n-decane using a surface force apparatus which has been modified to improve its sensitivity for detecting a weak and long-range force. Modifications include a magnetic drive system, the use of a weak cantilever spring with the apparatus mounted in a vertical configuration, and a detailed consideration of the interference optics to allow accurate measurements of surface separations up to several micrometers. The results show a repulsion that is well fitted by theoretical curves based on a model in which only counterions enter the calculation, in other words, in the absence of a reservoir of ions in the solvent. Fitting the theory to the data allows an estimate of the mica surface charge density of ∼1 mC/m². A mechanism for surface charging of mica in this solution is proposed, which includes a role for trace amounts of water that are inevitably present and adsorbed surface aggregates of AOT. The relevance of the results to previously observed charge stabilization of colloids in nonaqueous solvents is discussed.

Soft matter : from shapes to forces on the nanoscale

Soft matter deforms in response to imposed external forces. Here we demonstrate how dynamic surface forces are linked to far-field deformations. This offers a new paradigm for determining forces between soft particles in colloidal systems. The particular example we use to illustrate this concept is that of a fluid drop interacting with a solid wall through hydrodynamic drainage flow coupled with repulsive or attractive dissimilar electrical double layer interactions. The force can be deduced from a simple analysis of the drop surface geometry outside the interaction zone.

Forces between mica surfaces in ethylene glycol

Measurements are presented of the force as a function of separation between two molecularly smooth mica surfaces immersed in ethylene glycol, and in solutions of lithium chloride and sulfuric acid in ethylene glycol. At surface separations greater than 3 nm the measured force is in very good agreement with double-layer theory, but at smaller separations there is an oscillatory solvation force which is superimposed on the double-layer repulsion. In contrast to the case in water, the adsorption of hydrogen ions at the mica surface does not markedly affect the short-range forces.
