Using the Box-Cox regression model with heteroscedasticity (BCHR), we re-examine the size distribution of the Portuguese manufacturing firms studied by Machado and Mata (2000) using the Box-Cox quantile regression (BCQR) method. We show that the BCHR model compares favourably against the BCQR...

This paper considers tests of misspecification in a heteroscedastic transformation model. We derive Lagrange multiplier (LM) statistics for (i) testing functional form and heteroscedasticity jointly, (ii) testing functional form in the presence of heteroscedasticity, and (iii) testing...

Compared with technical research on ships, there is lack of systematic data and research on maritime labour, their number, education and manning efficiency. Due to the high mobility of the profession and complication of jurisdictions, there is no exact figure of the number of seamen worldwide....

By examining 20 years data, the paper attempts to outline the safety and quality records of open registers, and to establish a relationship of accidental total loss rate with ship quality factors, e.g., certificate, crew performance and equipment indicated by detention rates. It confirms that...

The paper is to explore the relation between national economic development and the formulation of maritime policy. It collects and examines data from 30 maritime nations, and shows that maritime policy is determined by economic circumstance rather than the result of rational decision of policy...

This study reveals areas where IMO regulations of safety of life at sea can be improved upon. After examination of 5389 mortality and 3559 accident cases of UK seamen and 6878 fatalities of worldwide seamen, it finds fatalities due to personal accidents on board ship constitute ∼90% of all...

This Paper introduces a new method of calculation on the number of accidental deaths among seafears world-wind Provided with completed data, a more accurate and reliable estimation is given.

The study examines 20-years of data on 36 world principal fleets and on worldfleets in general, analyses their developments, and particularly their safety records in terms of accidental total loss rates. This study confirms that the open-registry ships tend toward substandard ships. However,...
