Managing in the middle: a review of the mddle management experience in the 21st century

Downsizing and organisational restructuring have impacted both the role and the number of middle managers in organisations. .This paper provides a review of recent research on middle management to seek an understanding of the current situation for middle managers as they face the start of the 2rt century. The literature review is presented in two parts - focusing on the position of middle managers as they emerge from downsizing, and drawing attention to the special circumstances for managers "in the middle". The research points to some of the challenges middle managers' experience as they work, live, and survive organisational life, as well as highlighting the need for ongoing investigation of their individual experiences.

Unlocking Australia's relationship with the Middle East

Historically, Australia’s interests in the Middle East related primarily to its role in the Commonwealth imperial defence system which resulted in the deployment of Australian forces in the Middle East during both the First and Second World Wars. Similarly, the current involvement of Australian troops in Iraq and Afghanistan is driven by the country’s strategic alliance with the United States. However, Australia’s current involvement reflects a multifaceted relationship that spans economic, political and strategic spheres. Yet it is at the level of cultural and civilisational contacts that this relationship appears at its most vulnerable. This paper argues that a deeper understanding of this cultural dimension combined with a broader emphasis on good governance and human rights would be conducive to more robust ties in the longer term.

Soft-sediment deformation structures interpreted as seismite from the Middle Permian of the southern Sydney Basin, southeastern Australia

The Middle Permian Wandrawandian Siltstone of the southern Sydney Basin is well exposed along the coastline from Lagoon Head in the south to North Head in the north near Ulladulla in southern New South Wales. The unit is dominated by fossiliferous siltstone and mudstone, with abundant dropstones and minor pebbly sandstone interbeds, and contains an interval of well-preserved and extensive soft-sediment deformation structures. These deformation structures occur mainly in the middle part of the cliff sections and are bounded above and below by undeformed sedimentary units of similar lithology. A wide range of soft-sediment deformation structures have been observed, including cracks, sandstone and sandy mudstone dykes, a possible sand volcano, networks of relatively small and closely connected fissure-like structures, metre-scale complex-type slump folds, flexural stratification, concave-up depressional structures, small-scale normal faults (with displacements usually <1 m), shear planes, and breccias (pseudonodules). The slumps and associated deformations are here collectively interpreted as representing a seismite deposit attributable to penecontemporaneous deformation of soft, hydroplastic sediment layers following a liquefaction triggered by seismic shocks. The timing of the inferred earthquake events appears to correspond to the onset of a major basin-wide tectonism during the Middle Permian.

Housing price diffusion pattern of Australia's state capital cities

The ripple effect of house prices within metropolitan areas has recently been recognised by researchers. However, it is very difficult to formulate and measure this effect using conventional house price theories particularly in consideration of the spatial locations of cities. Based on econometrics principles of the cointegration test and the error correction model, this research develops an innovative approach to quantitatively examine the diffusion patterns of house prices in mega-cities of a country. Taking Australia's eight capital cities as an example, the proposed approach is validated in terms of an empirical study. The results show that a 1-1-2-4 diffusion pattern exists within these cities. Sydney is on the top tier with Melbourne in the second; Perth and Adelaide are in the third level and the other four cities lie on the bottom. This research may be applied to predict the regional housing market behavior in a country.

A panel cointegration analysis of the demand for oil in the Middle East

This article applies recently developed panel unit root and panel cointegration techniques to estimate the long-run income and price elasticities for oil in the Middle East. The results for the panel indicate that demand for oil is highly price inelastic and slightly income elastic in the Middle East. There is considerable variation in the results for the income variable across countries, with the coefficient on the income variable statistically insignificant for several countries. The coefficient on the price variable is statistically significant in all cases with the expected sign and the price elasticity is uniformly low. While the results for the income variable differ across countries, the results for the panel as a whole suggest that the demand for oil in the Middle East is being driven largely by strong economic growth, while consumers are largely insensitive to price changes.
