Pre-exercise carbohydrate and fat ingestion : effects on metabolism and performance

A key goal of pre-exercise nutritional strategies is to maximize carbohydrate stores, thereby minimizing the ergolytic effects of carbohydrate depletion. Increased dietary carbohydrate intake in the days before competition increases muscle glycogen levels and enhances exercise performance in endurance events lasting 90 min or more. Ingestion of carbohydrate 3-4 h before exercise increases liver and muscle glycogen and enhances subsequent endurance exercise performance. The effects of carbohydrate ingestion on blood glucose and free fatty acid concentrations and carbohydrate oxidation during exercise persist for at least 6 h. Although an increase in plasma insulin following carbohydrate ingestion in the hour before exercise inhibits lipolysis and liver glucose output, and can lead to transient hypoglycaemia during subsequent exercise in susceptible individuals, there is no convincing evidence that this is always associated with impaired exercise performance. However, individual experience should inform individual practice. Interventions to increase fat availability before exercise have been shown to reduce carbohydrate utilization during exercise, but do not appear to have ergogenic benefits.

Linking environmental uncertainty to non-financial performance measures and performance : a research note

Several previous research studies have reported mixed results concerning the direct association between non-financial performance measures and  performance. The presence of environmental uncertainty on this relationship has not been established. This paper makes a contribution to this area by proposing that it is in conditions of environmental uncertainty that non-financial measures are most useful in improving organizational performance. It analyses empirical data from a sample of New Zealand manufacturing organizations to test the hypothesis that non-financial measures of performance would lead to improved organizational performance under conditions of increased environmental uncertainty. Multiple regression analysis of the data suggests that performance should be a declining function of the size of the ‘mismatch’ between an organization's environment and use of the different combinations of non-financial performance measures. Further, the paper concludes that prior mixed results may be attributed to the omission of environmental uncertainty.

Power plays : Australian theatre and the public agenda

Power Plays capitalises on this moment of renewed and heightened interest by investigating the why and the how of eight contemporary Australian playwrights: Andrew Bovell, Patricia Cornelius, Reg Cribb, Ben Ellis, Wesley Enoch, Hannie Rayson, Stephen Sewell and Katherine Thomson. These writers are passionate about the theatre as a forum for public discussion and they interrogate current issues in their work. Their plays reflect the passing show of cultural, political and economic life in Australia, telling audiences something critical about what is going on: this is the state of play, this is what we are.

The author has conducted extensive interviews with these writers and offers an extended analysis of some of their recent plays.

Directors' remuneration and performance in Australian banking

This paper explores the relationship between directors' pay and performance within Australian banking, using panel data for the 1992-2005 period. The relationship between CEO pay and performance is investigated also. Several earnings models are estimated, using different dependent variables, alternate measures of performance and different estimation techniques. The results indicate an absence of a contemporaneous relationship between directors' pay and bank performance, and no association with prior year performance. However, there is a more distant pay-performance relationship, with total directors' pay having a robust positive association with earnings per share lagged two years, as well as with ROE lagged two years. The other key determinants of directors' pay in Australian banking are bank specific managerial policies, lags in the administration of pay, bank size, directors' age and directors' stock ownership. In contrast to total directors' pay, the evidence confirms a strong positive and direct association between CEO remuneration and prior year bank performance. The pay-performance association is stronger and more direct for CEO remuneration than it is for total directors' remuneration. The responsiveness of CEO pay with respect to bank performance appears to have increased over time.

The glue that binds : workplace climate, human resource systems and performance

There is now a substantial body of research examining the relationship between human resources (HR) and organisational performance. During the last decade, this research has focused on the impacts of ‘bundles’ of HR practices. While researchers have consistently found a significant relationship between HR systems and performance, the mechanisms that give rise to this relationship remain poorly conceptualised. Building on the work of Barney (1998), Ferris et al. (1998) and Bowen and Ostroff (2004) we suggest the social context in which such practices are implemented provide the basis for specifying these transmission mechanisms. Workplace climate provides a key social context that induces high levels of effort and dynamic efficiency. Using a large sample we find workplace climate significantly influences the relationship between HR systems and performance.

Directors' remuneration and performance in the Australian banking sector

This paper explores the links between directors' pay and performance within the Australian banking sector using panel data for the 1993-2004 period. The links between CEOs' pay and performance is investigated also. Several earnings models are estimated and different estimation techniques are used. The results indicate that there is no link between directors' pay and firm performance with a one year lag. However, there is a more distant payperformance link, with directors' pay influenced by shareholders' returns with a three year lag. The other key determinants of directors' pay in the Australian banking sector are bank specific managerial policies, lags in the administration of pay, bank size and board composition. A clear and strong positive and direct association between CEO remuneration and performance is established.

Psychic distance : antecedents, retail strategy implications and performance outcomes

The authors propose a conceptual model of the psychic distance–organizational performance relationship that incorporates organizational factors (international experience and centralization of decision making), entry strategy, and retail strategy implications. The findings suggest that when entering psychically distant markets, retailers should adopt low-cost/low-control entry strategies and adapt their retail strategy to a greater extent than in psychically close markets. However, the authors find that such strategic responses have an adverse effect on performance. They find that international experience, psychic distance, entry strategy, and retail strategy adaptation are significant drivers of organizational performance and factors that determine critical success in international retailing.

Icon and markor : links and performance in South African firms

Market orientation and innovation orientation are two concepts that seem to contradict each other. Whether they intend to or not, firms adopt a strategic mode of focus, a way of directing efforts towards markets, products, both, or neither. However, little information exists on whether managers within these organizations are content with the strategic archetype they have adopted, and if not, what their preferred mode of focus would be. This paper reports the results of a study that identified the modes of focus of South African firms as perceived by senior marketing managers, and then matched these to their preferences. Limitations are identified, implications for management singled out, and avenues for future research highlighted.
