Hundreds of millions of pages of microfilmed historical documents are not being digitised at this time due to insufficient individual demand to garner appropriate commercial attention and investment.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 To explore this question empirically, I combined data from ship records with data from various historical documents reporting slave ethnicities, and construct estimates of the number of slaves exported from each country during Africa’s slave trades between 1400 and 1900.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With the increasing number of documents that are available in digital form, also the number of digital historical documents is increasing (Berkvens, 2001). It cannot be assumed that standard IR systems perform well on historical documents: historical texts differ from modern texts in three ways (Hüning, 1996; Van Der Horst and Marschall, 1989): (a) vocabularies have changed, (b) spelling has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...

Statistical methods for the use of historical control data in testing for a trend in proportions in carcinogenicity rodent bioassays are reviewed. Asymptotic properties of the Hoel-Yanagawa exact conditional tests are developed and compared with the Tarone test. It is indicated that the Hoel-Yanagawa test is more powerful than the Tarone test. These tests depend on the beta-binomial parameters ...

In this paper, we discuss the historical and current perspectives on women in computer science and the recent downward trend of women's participation in this field We then present results from a survey that asked respondents their views on why women's participation in the field of computing is decreasing, what we can do to reverse this trend, and what they predict the future holds for women in ...

A survey on opium use was earned out in Tinsukia district of upper Assam to assess the present prevalence and pattern of opium abuse and compared with earlier findings of the year 1981 (Baruah et al., 1995). A total of 75 addicts could be detected during the survey and 61 were interviewed using structured questionnaire. The results indicate significant decline in prevalence in opium use over th...

We report the first spectroscopic evidence for a [C-F-C]+ fluoronium ion in solution. Extensive NMR studies (19 F, 1 H, 13 C) characterize a symmetric cage-like species in which fluorine exhibits substantial covalent bonding to each of the two carbon atoms involved in the three-center interaction. Experimental NMR data comport well with calculated values to lend credence to the structural assig...
