Adaptive bayesian analysis for binomial proportions
(Economic Research Southern Africa, 2008-10) Das, Sonali; Das, Sonali
The authors consider the problem of statistical inference of binomial proportions for non-matched, correlated samples, under the Bayesian framework. Such inference can arise when the same group is observed at a different number of times with the aim of testing the proportion of some trait. For example, say, we are interested to infer about the effectiveness of a certain intervention teaching strategy, by comparing proportion of ‘proficient’ teachers, before and after an intervention. The number of teachers may differ between the two measurement time points, due to any number of reasons, and thus can result in an unequal number of observations in two periods. For such nonmatched design, we develop an adaptive Bayesian method, and suggest a heuristic decision procedure to conduct statistical inference. The authors use the -divergence measure to quantify the perturbation of the posterior distribution of the proportion in different time points. They present a simulation study to compare the statistical power between the adaptive Bayesian method and the existing frequents method. Their study and theoretical results indicate that under certain design, the adaptive Bayesian method outperforms the existing method. They administer the developed adaptive Bayesian method to two case studies.
Application of systems engineering: An acquisition agent perspective
(INCOSE EMEA, 2014-10) Niken, A; Erasmus, Louwrence D
This article covers a descriptive case study on the application of systems engineering and systems engineering management at Armscor. The report also covers the investigation into development methods used and the how the requirements changes are managed during the concept phase. The systems engineering process model used by Armscor is compared with best practice. The Systems Engineering Management Base Theory (SEMBASE) model is used to compare the Armscor systems engineering management practice with. The study encompassed development methods, requirements management change, design for changeability and use of tools. Research questions are addressed by narrative analysis. Data is collected from multiple sources: interviews, archival records documentation and observations of enterprise governance documentation. The data produced during the inquiry revealed that a correlation exists between systems engineering best practices, international standards, the systems engineering process and systems engineering management process followed by Armscor. Requirements changes are managed during the concept Phase and different developmental models are used to execute projects.

A comparison of the cost associated with pollution prevention measures to that required to treat polluted water resources
(2012-03) Oelofse, Suzanna HH; Roux, S; De Lange, Willem J; Mahumani, B; Le Roux, Wouter J; Du Preez, M; Greben, HA; Steyn, Maronel
Pollution of water resources is largely as a result of human activity and therefore could be prevented to a large degree. The quality of our water resources is deteriorating and downstream water users have to deal with the pollution impacts caused by upstream uses. This situation have resulted in a debate as to whether it will not make more economic sense for water users to treat water for use rather than to meet discharge standards. There are instances where discharge standards require water of a better quality to be released than what was abstracted for use in the first place. However, the National Water Act, 1998 places the responsibility for pollution prevention and remediation on the polluter, not the user. The development of the Waste Discharge Charge System (WDCS) is aimed at providing economic incentives and penalties for polluters to pay in accordance with the “polluter-pays-principle”. The general objective of the study was to compare the costs associated with measures to control pollution at source with those required to treat the consequences associated with polluted water for salinity, eutrophication, microbial pollution and sediments.
