We have examined DNA sequence error as a function of length using both a manual method of performing reactions with Sequenase and an automated Taq cycle sequencing method. DNA fragments from both methods were separated and analyzed on a sequencer. To determine the sequence of a cosmid insert (35.3 kb), 379 sequences were obtained from a manual Sequenase(More)
Remote-sensing techniques are now being used routinely in geologic interpretation for mineral and energy exploration, plant siting, waste disposal, and the development of models for regional and continental tectonics. New spaceborne methods and associated technologies are being developed to produce data from which geologic information about large areas can(More)
Despite more than 30 years of gender reform in schools, the percentages of girls enrolled in information technology subjects in the post-compulsory years of education has remained persistently low: often under 25%. This article investigates data collected during an Australian Research Council Linkage Grant project (2005-2007) focused on identifying the(More)
The percentages of girls in developing countries studying information technology subjects in the post-compulsory years of education has remained persistently low: often under 25%. This is despite the fact that this particular phenomenon has been the subject of international enquiry for over two decades. The persistence of this pattern raises questions about(More)
High-resolution photographs returned by Orbiters II and III typically show a surface pitted with small, perfectly circular craters as much as 50 meters in diameter, some of which are strongly clustered; these are superposed on larger, generally shallower craters and must be a mixture of primary and secondary impact craters. Rough terrain is less heavily(More)
How innovations in tertiary education are theorised and understood is important for both policy and practice. This paper describes an approach to studying innovation and change that is taken from the field of Science and Technology Studies. Actor-network theory draws attention to the performative nature of the implementation of new technologies like quality(More)
