This study looked at the effect of a number of factors such as the choice of analytical method, the handling method for missing data, sample size, and proportion of missing data, in order to evaluate the effect of missing data treatment on accuracy of estimation. In order to accomplish this a methodological approach involving simulated data was…

This dissertation develops a deeper understanding of the epistemic values of scientists, specifically exploring the proposed values of community, collaboration, connectivity and credit as part of the scholarly communication system. These values are the essence of scientists actively engaged in conducting science and in communicating their work to…
