What constitutes success in telehealth?

Before telehealth applications can be judged, there must be some general understanding about what constitutes success. At first sight it seems that defining success in a telehealth application should be relatively easy: a successful application is one that produces high-quality care at low cost. However, the calculation of cost requires some care, since it depends on assuming a particular financial perspective (the patient's, the health-care provider's, or society's) and is meaningless without a statement of the workload being handled. Other factors include the context in which the service is being delivered. Ultimately, the political imperative may override any rational judgement of success.

The point-of-referral barrier - a factor in the success of telehealth

A feasibility study was carried out to test the hypothesis that, for an effective telehealth service, a full-time coordinator is required to act as a single point of contact for consultation requests. By shifting the responsibility for telepaediatrics from the referrer to the provider, the telehealth process becomes equally (or more) attractive as the conventional alternative. Preliminary results showed that, within six months, telepaediatric activity increased to an average of 8 h per month. Not only did certain health services become more accessible to children and their families in remote areas of Queensland, but significant savings were also made. At least 12 patient transfers were avoided to and from the tertiary facility, with an estimated minimum saving of $18,000 to the health-care provider.

State Banks and Economic Development in China

State-owned banks remain dominant in China's financial sector despite over two decades of gradual financial liberalization. Their performance is typically evaluated using commercial banking criteria. The standard view is that because state banks have experienced declining profitability and capital adequacy, they have been a drain on past economic development and endanger future growth prospects. However, we argue that state banks have strong development bank characteristics and hence warrant different performance criteria. The analysis in this paper suggests that while thier commercial performance may have been poor, the overall impact of state banks on China's economic development appears to have been both positive and sustainable.

Estimating economic relationships subject to firm- and time-varying equality and inequality constraints

Applied econometricians often fail to impose economic regularity constraints in the exact form economic theory prescribes. We show how the Singular Value Decomposition (SVD) Theorem and Markov Chain Monte Carlo (MCMC) methods can be used to rigorously impose time- and firm-varying equality and inequality constraints. To illustrate the technique we estimate a system of translog input demand functions subject to all the constraints implied by economic theory, including observation-varying symmetry and concavity constraints. Results are presented in the form of characteristics of the estimated posterior distributions of functions of the parameters. Copyright (C) 2001 John Wiley Sons, Ltd.

Postmaterialist and economic voting in Australia, 1990-98

Recent research in Australian sociology and political science has debated the extent to which postmaterialist values and economic self-interest shape voting in federal elections. Some researchers have argued that postmaterialist values have partly displaced materialist concerns with physical security and economic well-being in Australian public life. This displacement, coupled with the adoption by major political parties of postmaterialist 'quality of life' issues such as the environment, has meant that voting in Australia has come to be more dependent on postmaterialist values than on perceptions of economic interest. Other research, however, has found no relationship between postmaterialist values and voting behaviour, while economic evaluations remain a strong determinant of voting behaviour. Part of the disagreement reflects methodological differences in the research. But different methodological problems compromise each of the previous studies. In this paper we use data from the 1990, 1993, 1996 and 1998 Australian Election Studies to investigate postmaterialist and economic voting in the Commonwealth House of Representatives and the Senate. Using various statistical methods, we first explore bivariate relationships between key variables and then use multivariate models of postmaterialist and economic voting to adjudicate between the contending positions.
