The paper attempts to throw light on the direct (instructional) cost of OU teaching methods as against conventional “live” instruction. The variable cost per student-course is with one exception lower in the OU than elsewhere. This constitutes a strong case for the use of existing OU packages in campus universities, especially as campus universities might feel able to dispense with the costs of the summer schools. It also constitutes a case for expansion of existing courses at the OU. As regards the development of new OU packages, the paper shows the Foundation courses to be much cheaper than equivalent provision de novo at the same scale in campus universities. Measured by the breakeven number of students, second-level courses in a given faculty are cheaper than foundation level courses. But they also have fewer students and some are operating at levels which, if there were no interdependence between courses, might be considered expensive. If however they were used by more students either at the OU or at campus universities they could be economic, even when taken on their own. The paper does not cost student time but, if this is cheaper when OU teaching methods are used, this is a further argument in their favour.
相似文献This paper argues that journalists’ discursive actions in an outbreak context manifest in identifiable rhetorical motifs, which in turn influence the delivery of biomedical information by the media in such a context. Via a critical approach grounded in rhetorical theory, I identified three distinct rhetorical motifs influencing the reportage of health information in the early days of the H1N1 outbreak. A public-health motif was exhibited in texts featuring a particular health official and offering the statements of such an official as a mechanism of reassurance. A concealment-of-information motif was exhibited in texts emphasizing the importance of the transparency of health officials, and in texts demonstrating ambivalence about information provided by socially-sanctioned sources. Finally, in texts mythologizing the outbreak to the exclusion of other functions of the text (e.g., conveying who is at risk, protective behaviours, symptoms), I identified a pandemic motif. Each motif differs in the conclusions it offers to audiences seeking to gauge relative levels of risk, and to receive information about protective behaviours. I suggest that one means of interpreting the manifestation of distinct rhetorical motifs in the context of a high-risk health threat is the certainty that this context alters moral responsibilities, consequently influencing the manifestation of narrative role.
