"The Problem of Spatial Autocorrelation" and Local Spatial Statistics   总被引:2,自引:0,他引:2  
This article examines the relationship between spatial dependency and spatial heterogeneity, two properties unique to spatial data. The property of spatial dependence has led to a large body of research into spatial autocorrelation and also, largely independently, into geostatistics. The property of spatial heterogeneity has led to a growing awareness of the limitation of global statistics and the value of local statistics and local statistical models. The article concludes with a discussion of how the two properties can be accommodated within the same modelling framework.  相似文献

Why do policies fail? There are many answers to this question, and many ways of answering it. In this paper, we use the tools of policy framing and systems thinking to investigate two recent Australian examples of public policy failure, each involving a different policy milieu and time-span. We show that, in both these cases, unintended consequences arose because governments lost control of the implementation process while remaining politically accountable for the outcomes. We develop the concept of transmitted risk to show how this occurred. We argue that governments expose themselves to this kind of risk when they make policy decisions involving a combination of excessive incentives and poorly controlled third parties.  相似文献

If placebos have been squeezed out of medicine to the point where their official place in in clinical trials designed to identify their own confounding effect, the placebo effect nevertheless thrives in psychotherapy. Not only does psychotherapy dispose of placebo effects that are less available to medicine as it becomes increasingly technological and preoccupied with body parts, but factors of the sort inhibiting the use of placebos in medicine have no equivalent in psychology. Medicine today is disturbed by the placebo effect in a way psychotherapy is not. Psychotherapy does not have to grapple with such a disconcerting paradox as successful sham surgery, and unlike those physicians who once pretended to treat the patient's body while actually attempting to treat the mind, the psychotherapist can treat the mind in all frankness. Perhaps it is because psychotherapy is less burdened by doubts about the placebo effect that it was able to come to its aid when it was orphaned by medicine. It is vain to expect something with so long a history as the placebo effect to disappear from the practices of healing.  相似文献

During new excavations at the preceramic rockshelter of Casita de Piedra in western Panama, a cache of 12 unusual stones was recovered near the back wall, dating to between 4800 and 4000 cal bp. The stones include quartz, pyrite, a chalcedony vein nodule, a bladed quartz and jarosite aggregate and a human-modified dacite cylinder. Based on the unusual lithic types and the context of the cache, we suggest that these stones once belonged to a ritual specialist, such as a healer or shaman. Special stones are frequently mentioned as being an important component of a shaman’s ritual paraphernalia in ethnographic records of various historic Native American groups throughout Central and South America, including the Bribri and Cabécar of southeastern Costa Rica and western Panama (formerly known as the ‘Talamanca’). The cache of stones recovered at Casita de Piedra may represent the earliest material evidence in Central America of shamanistic practice.  相似文献

Abstract

The collapse of empires is exceedingly difficult to understand. The author examined the distribution of imperial lifetimes using a data set that spans more than three millennia and found that it conforms to a memoryless exponential distribution in which the rate of collapse of an empire is independent of its age. Comparing this distribution to similar lifetime distributions of other complex systems—specifically, biological species and corporate firms—the author explores the reasons behind their lifetime distributions and how this approach can yield insights into empires.  相似文献
