The phenomenon of the shortage of rural workers is a response of labor market to rapid export growth and economic growth after China became a WTO member. It not only indicates a transition of China’s rural surplus labor forces from unlimited supply to limited surplus, but also highlights the urgent need for an integrated national labor market to solve the structural issue of segregated local la...

One of the most important requirements of microgrid operation is to maintain a constant frequency such as 50 Hz or 60 Hz, which is closely related to a power balance between supply and demand. In general, microgrids are connected to power grids and surplus/shortage power of microgrids is traded with power grids. Since islanded microgrids are isolated from any power grids, the decrease in genera...

This essay examines the relationship that Paul Starr hypothesized in The Social Tranformation of American Medicine (1982) between the supply of physicians (both allopaths and osteopaths) and their professional dominance, a relationship, he argued, that began to turn negative about the time of the passage of Medicaid and Medicare in 1965. In particular, Starr posited that an increasing number of...

The paper uses the Lewis model as a framework for examining the labour market progress of two labour-abundant countries, China and South Africa, towards labour shortage and generally rising labour real incomes. In the acuteness of their rural-urban divides, forms of migrant labour, rapid rural-urban migration, and high and rising real wages in the formal sector, the two economies are surprising...

For many researchers involved in fusion power plant development, the issue of tritium selfsufficiency is of particular concern because of the danger of placing the plant fuelling at risk. The tritium (T) bred in the blanket should be estimated fairly accurately as an uncertainty as small as 1% translates into 1-2 kg of T per FPY for 2-3 GW fusion power. This has a significant impact that is imp...

Declining reservoir storage has raised the specter of the first water shortage on the Lower Colorado River since the completion of Glen Canyon and Hoover Dams. This focusing event spurred modeling efforts to frame alternatives for managing the reservoir system during prolonged droughts. This paper addresses the management challenges that arise when using modeling tools to manage water scarcity ...

The National Primary Health Care Strategy in Australia recommends primary health care services need to be clinically and culturally appropriate and delivered in a timely and affordable manner. However simultaneously recognised, access is still inequitable in among various population groups and many areas of Australia. Geographical Information System (GIS) have been used to explore geographical ...

We characterize the incentive compatible allocation that maximizes the expected social surplus in a single-unit sale when the efficient allocation is not implementable. We then show that allowing for the possibility that the good remains unsold may increase the expected social surplus even when allocating the good to no bidder generates less social surplus than allocating to any of the bidders....
