Hundreds of millions of pages of microfilmed historical documents are not being digitised at this time due to insufficient individual demand to garner appropriate commercial attention and investment. This paper demonstrates that the cost of digitisation and online delivery can be lowered dramatically using a novel application of recent technological advancements in imaging, data processing and ...

A convertible bond is defined to be (e.g., Jorion [10]) a bond issued by a corporation that can be converted into the equity of that corporation at certain times using a predetermined exchange ratio. This entails the creation of new shares issued by the corporation if and when conversion occurs, and the existing shares are diluted by the creation of the new shares. The option to convert is sole...

Can part of Africa’s current underdevelopment be explained by its slave trades? To explore this question empirically, I combined data from ship records with data from various historical documents reporting slave ethnicities, and construct estimates of the number of slaves exported from each country during Africa’s slave trades between 1400 and 1900. I find a strong robust negative correlation b...

With the increasing number of documents that are available in digital form, also the number of digital historical documents is increasing (Berkvens, 2001). It cannot be assumed that standard IR systems perform well on historical documents: historical texts differ from modern texts in three ways (Hüning, 1996; Van Der Horst and Marschall, 1989): (a) vocabularies have changed, (b) spelling has ch...

In the planning and design of new clinical trials, calculation of the required sample size and power is a critical part of the process. Power calculations are usually based on quantities estimated from analysis of historical data and are therefore subject to uncertainty. In many cases this is addressed by sensitivity analysis, but simple sensitivity analysis gives an incomplete picture of the u...

The literature on rheumatic diseases is enormous; yet the whole subject seems to be shrouded in a fog, while treatment furnishes the most lucrative field for quackery of every kind. The differentiation and nomenclature of the conditions commonly grouped together under the designation ' rheumatic' still furnishes the ground for differences of opinion which only bewilder a general practitioner.
