A sustainable agricultural landscape for Australia: A review of interlacing carbon sequestration, biodiversity and salinity management in agroforestry systems

Transformation of the south-western Australian landscape from deep-rooted woody vegetation systems to shallow-rooted annual cropping systems has resulted in the severe loss of biodiversity and this loss has been exacerbated by rising ground waters that have mobilised stored salts causing extensive dry land salinity. Since the original plant communities were mostly perennial and deep rooted, the model for sustainable agriculture and landscape water management invariably includes deep rooted trees. Commercial forestry is however only economical in higher rainfall (>700 mm yr−1) areas whereas much of the area where biodiversity is threatened has lower rainfall (300–700 mm yr−1). Agroforestry may provide the opportunity to develop new agricultural landscapes that interlace ecosystem services such as carbon mitigation via carbon sequestration and biofuels, biodiversity restoration, watershed management while maintaining food production. Active markets are developing for some of these ecosystem services, however a lack of predictive metrics and the regulatory environment are impeding the adoption of several ecosystem services. Nonetheless, a clear opportunity exists for four major issues – the maintenance of food and fibre production, salinisation, biodiversity decline and climate change mitigation – to be managed at a meaningful scale and a new, sustainable agricultural landscape to be developed.

Customer retention management in the recession

The purpose of this article is to explore customer retention strategies and tactics implemented by firms in recession. Our investigations show just how big a challenge many organizations face in their ability to manage customer retention effectively. While leading organizations have embedded real-time customer life cycle management, developed accurate early warning systems, price elasticity models and ‘deal calculators’, the organizations we spoke to have only gone as far as calculating the value at risk and building simple predictive models.

Human resource allocation management in multiple projects using sociometric techniques

This article describes a new application of key psychological concepts in the area of Sociometry for the selection of workers within organizations in which projects are developed. The project manager can use a new procedure to determine which individuals should be chosen from a given pool of resources and how to combine them into one or several simultaneous groups/projects in order to assure the highest possible overall work efficiency from the standpoint of social interaction. The optimization process was carried out by means of matrix calculations performed using a computer or even manually, and based on a number of new ratios generated ad-hoc and composed on the basis of indices frequently used in Sociometry.

Earnings management in firms seeking to be acquired

Empirical evidence regarding accrual-based earnings management around mergers and acquisitions has been setting-specific as far as target firms are concerned. This might be due to the fact that target firms cannot always anticipate an acquisition proposal, and thus lack the motive and the time necessary to manage their earnings in order to facilitate or impede the deal. In this paper, we provide clear evidence of downward earnings management by a sample of target firms that have both time and motive to engage in such actions. These are firms that publicly announce their intention to be acquired. Publicly ‘seeking a buyer’ represents a rather unusual corporate event, and we find that these firms engage in downward earnings management in the years surrounding the ‘announcement year’. To some extent, this result is explained by overrepresentation of low performance and growth among these firms, and it can be interpreted under alternative explanations. Furthermore, we show that such downward earnings management negatively affects the probability for a ‘seeking buyer’ firm to secure an acquisition within a reasonable amount of time, a possible indication of efficient diligence by prospective buyers having a preference for firms ‘seeking buyer’ with no informationally obscure earnings.
