Available studies have not provided a satisfactory answer to the problem of making international comparisons of port efficiency. This study applies data envelopment analysis (DEA) to provide an efficiency measurement for four Australian and twelve other international container ports. While DEA has been applied to a wide number of different situations where efficiency comparisons are required, this technique has not previously been applied to ports. The DEA technique is useful in resolving the measurement of port efficiency because the calculations are non-parametric, can handle more than one output and do not require an explicit a priori determination of relationships between output and inputs, as is required for conventional estimation of efficiency using production functions. The ports of Melbourne, Rotterdam, Yokohama and Osaka are found to be the most inefficient ports in the sample, based on constant and variable returns to scale assumptions, mainly due to the enormous slack in their container berths, terminal area and labor inputs. The study also draws some policy implications for ports and recommends certain areas for future research. Previous article in issue.

WeatherBug Editor's ReviewKeep track of weather on your PC with WeatherBug.The weather is often a funny thing. No one ever, EVER seems to get it right until its nearly right on top of you. However, keeping track of it, knowing what the weather may be, is something that most everyone wants to know.
This is one of the biggest reasons why I like WeatherBug. It’s a multi-platform weather utility.WeatherBug desktop helps you keep track of current, local weather conditions, extended forecasts, and severe weather alters.
Its animated Doppler radar maps are exceptionally valuable in severe weather conditions, as are its satellite and temperature maps. The best thing about WeatherBug desktop is that it works on just about any computer you can throw at it.On the Windows side, WeatherBug has its traditional desktop app, but also desktop gadgets for both Windows Vista and Windows 7 Side Bars. On the mac, WeatherBug Alert for Mac provides live temperatures and desktop alerts.
On both platforms,you'll have access to live, local current conditions, 7-day, hourly and weekend forecasts, animated radar and maps as well as severe weather alters.Pro’s: Free, informative, multiplatformCon’s: Free version is ad supportedConclusion: WeatherBug is a great application suite. It provides a great service and very valuable information. Its gadgets, may or may not be working any longer, as of this writing, Microsoft has ended support for its Side Bar due to security concerns. The rest of its components, however, are fine and again, provide valuable information. This is a must have app on any Mac or Windows PC. WeatherBug Publisher's Description.
