Assessing and acquiring technology does not have to be chaotic, driven solely by price, clinical preference, and emotion. With the tools available, it can be distilled to a process of organized common sense, which results in maximum flexibility for the user and allows materiel managers to procure the best, most cost-effective equipment for the hospital. 相似文献

For an arbitrary subset A of the finite state space 5 of a Markov chain the so–called embedded matrix P A is introduced. By use of these matrices formulas expressing all kinds of probabilities can be written down almost automatically, and calculated very easily on a computer. Also derivations can be given very systematically. 相似文献

A bstract . Justice in the economy is a subject of renewed interest among contemporary economists. In the growing literature, Joseph A. Spengler's Origins of Economic Thought and Justice may become a standard reference work. Its great merit is the way it handles values and value judgments. Economics as an objective science cannot tell us anything about ends, Spengler holds, but it illuminates Valuation and facilitates isolation of costs and some benefits of realizing ends. Still, economists "need to base their policy-oriented arguments on distributive justice and not on efficiency. " 相似文献

This article examines judicial and administrative rulings and legislation involving or related to the issue of drug testing in the workplace. It discusses the rights of employees in the public and private sector: constitutional rights; federal, state, and local statutory rights; rights of unionized employees; and common law rights. It analyzes both the current state of the law and future directions the law may take, as courts and administrative agencies decide more cases and governmental bodies continue to pass drug testing legislation. 相似文献

Polyhedral combinatorics is a subarea of combinatorial optimization of increasing practical importance. It deals with the application of the theory of linear systems and linear algebra to combinatorial problems. The paper is not intended as a survey on polyhedral combinatorics but it reviews some of the main concepts and proof techniques. 相似文献
