The objective of this paper is to understand what characteristics and features of clinical data influence physician's decision about ordering laboratory tests or prescribing medications the most. We conduct our analysis on data and decisions extracted from electronic health records of 4486 post-surgical cardiac patients. The summary statistics for 335 different lab order decisions and 407 medic...

Formal project management methods are largely organized around ensuring that the uncertain performance of activities suffices to meet fixed targets and requirements. In practice, requirements often change. Qualitative aspects of project management aim to anticipate and respond to the complications these changes create. This paper explicitly treat targets as uncertain. This allows the qualitativ...

In the following perspective, we will highlight seemingly remote, downstream consequences of common ventilator management decisions. For example, a change in PEEP may alter venous return, blood pressure, cardiac output, arterial and venous blood gas tensions, metabolic rate, respiratory sensations, breathing pattern, and the work of breathing. If providers consider any of these changes dangerou...

Efficient conservation management is particularly important because current spending is estimated to be insufficient to conserve the world's biodiversity. However, efficient management is confounded by uncertainty that pervades conservation management decisions. Uncertainties exist in objectives, dynamics of systems, the set of management options available, the influence of these management opt...

The simulation model APSFarm is an extended configuration of the systems model APSIM, and has been in development since 2005 to support the analysis of farm case studies in environments ranging from Central Queensland to the Victorian Riverina. One of the major extensions to APSIM was the implementation of dynamic farm management as a set of state transition networks, with each network represen...

Shipping companies frequently outsource the management of their vessels. In this paper, we use data from Lloyd’s Register Fairplay (2009) on 45,456 vessels belonging to 9,580 different shipowners to investigate the extent of outsourcing in shipping and to identify key factors affecting the likelihood of outsourcing. The results of our econometric analysis indicate that ship-owners’ decisions to...

A uscr friendly. personal computer-based system designed to help solve cash management problems is discussed. The system is a "smart" system that enables the cash manager to use analytic techniques that otherwise would not be as accessible to anyone other than a technical analyst. The system formulates a cash management problem as a network problem, solves that network problem. ensures feasibil...
