Biomedical ethicists often assume that common morality constitutes a largely consistent normative system. This premise is not taken for granted in general normative ethics. This paper entertains the possibility of inconsistency within common morality and explores methodological implications. Assuming common morality to be inconsistent casts new light on the debate between principlists and descr...

Decision Support Systems (DSS) that operate within a spatial or spatial–temporal context represent special forms of more general decision support systems. Their intent is to permit planners and policy makers to: (1) integrate large quantities of existing space–time data, (2) use these data as inputs to sophisticated forecasting models for predicting the results of alternative policy choices, an...

Although many researches have been carried out to analyze laboratory test errors during the last decade, it still lacks a systemic view of study, especially to trace errors during test process and evaluate potential interventions. This study implements system dynamics modeling into laboratory errors to trace the laboratory error flows and to simulate the system behaviors while changing internal...

The aim of this article is to review issues related to the incorporation of scarce natural resources in the theory of economic growth and development. More specifically, we shall concentrate on the role of non-renewable resources. A nonrenewable resource is a natural resource the amount of which on earth is finite and which has no natural regeneration process (at least not within a relevant tim...

The pigeonhole principle is a basic counting technique. It is illustrated in its simplest form as follows: We have n + 1 pigeons and n holes. We put all the pigeons in holes (in any way we want). The principle tells us that there must be at least one hole with at least two pigeons in it. Why is that true? Try to visualize the example of n = 2; therefore, we have 3 pigeons and 2 holes. Let’s try...

This paper presents the design philosophy used in the BEST/ 1 computer performance evaluator. Essentially, BEST/1 is a modeling tool which has been developed to address the "what if" questions that arise when evaluating computer . system performance. These questions are of importance in such areas as capacity planning, performance tuning, hardware vendor selection and new system design. From a ...

A meme media object, also known as a Webble, always come with a set of familiar generic behaviors together with another set of specialized ones for that particular Webble. But what if there is a need for a custom behavior or interface that was not originally intended when first created. With Webble technology, that does not need to be a problem. In this paper we will attempt to show how simple ...

Mapping apps are the greatest game-changer for encouraging people to explore the city. You take your phone out and you know immediately where to go. However, the app also assumes there are only a handful of directions to the destination. It has the power to make those handful of directions the definitive direction to that destination. A few years ago, my research started to focus on understandi...

JS McMillan Fisheries Ltd. (JSM) is a Vancouver-based commercial fishing, production and distribution company. As the operations of JSM evolved, the process of allocating a commercial salmon catch to a set of final products has become complex and time-consuming. We developed a linear programming based decision support tool to assist JSM management with this allocation decision. The decision sup...

ince the advent of computing, the world has experienced an information " big bang " : an explosion of data. The amount of information being created is increasing at an exponential rate. Since 2003, digital information has accounted for 90 percent of all information produced [1], vastly exceeding the amount of information on paper and on film. One of the greatest scientific and engineering chall...
