Towards A Framework For Mobile Information Environments: A Hospital-Based Example, Linda Dawson, Sea Ling, Maria Indrawan, Stephen Weeding, Juanita Femando
Associate Professor Linda Dawson
We propose a conceptual framework to describe and understand mobile information environments. In our proposal, such an environment can be categorised into different abstraction levels or communities: user level, workflow level, device level and architecture level. A hospital-based example is then used as an illustration for the proposed framework.

Faculty of Engineering and Information Sciences - Papers: Part A
Although asymptotically design-unbiased, GREG estimators may produce bad estimates. The article examines the behaviour of GREG estimators when the underlying models are misspecified. It shows how an efficient GREG estimator was found for a business survey that posed some problems. The work involved data exploration in several steps, combined with analyses of g-weights, residuals and standard regression diagnostics. We discuss two diagnostics for whether a GREG estimate is reasonable or not. A common justification for the use of GREG estimators is that, being asymptotically design unbiased, they are relatively robust to model choice. However, we show that the property of …
