In this note, I present a method to estimate the desired distance between medical facilities. The survival rate of patients improves when the facility is larger, however larger facilities result in a longer driving distance to the facility which decreases the survival rate. I identify the desired distance between facilities for which the survival rate is maximized. 相似文献

From the 17th to the 12th Century B.C. the Hittite Kingdom was one of the most notable powers in the Near East. It ranged over a vast geographical area dominating the surrounding cities and smaller states. Throughout this time the Hittites consistently developed their political system thereby ascending to the level of an empire. From sources pertaining to this era, it can be ascertained that already in the early stages, when the borders were not as extended, the Hittite Kingdom adopted the tradition of sending the king's sons and princes to the newly conquered regions and significant cities. 相似文献

A NOTE ON THE FORMULATION OF A FULL-ANALOGUE REGRESSION MODEL OF THE SHIFT-SHARE METHOD 总被引:1,自引:0,他引:1

ABSTRACT. This paper presents a full-analogue regression model of the deterministic shift-share method, for analyzing the components of regional employment change. The model is formulated as a constrained least squares regression problem. This leads to a direct determination of estimates for the national, industrial, and regional growth coefficients. The statistical significance of these coefficients and the overall model can then be tested by using standard regression test statistics. 相似文献

Evidence is presented that the clay in ancient ware fired at a temperature below 700–800°C becomes rehydrated over the millennia, such that it behaves somewhat like an unfired clay, rendering DTA a useful tool in identifying the clay minerals present. More recent samples can be artificially rehydrated by heating in a steam autoclave. 相似文献

ABSTRACT. Our study extends the standard comparative static analysis to allow for dynamic aspects of equilibrium in spatial competiton. We investigate dynamic stability properties via the Routh-Hurwitz criterion. Nontrivial equilibria in the so-called Löschian, Hotelling-Smithies, and Greenhut-Ohta models are shown to be stable even under heterogeneous cost conditions among competing firms, conditions not considered hitherto. We can thus provide powerful support to the comparative static analyses which can only be developed via equilibrium concepts with stability properties. 相似文献
