It is well established that using data summaries for a set of geographic areas or zones to estimate the parameters of a statistical model, commonly called ecological inference, frequently leads to the modifiable area unit problem (MAUP). In this article, the zoning effect of the MAUP is investigated for a range of scales. A zoning distribution is defined, and then used to characterize the zoning effect for parameter estimates from ecological analyses. Zone‐independent parameter estimates are obtained using the mean of the zoning distribution, and assessed using the variance of the zoning distribution. Zoning distributions are illustrated for parameter estimates from two ecological regression models at multiple scales using Australian National Health Survey data. For both a continuous response variable and a binary response variable, the empirical zoning distributions are unimodal, relatively symmetrical with appreciable variation, even when based on a large number of zones. The “ecological mean,” or expected value of the empirical zoning distribution at each scale, displays systematic variation with scale and the zoning distribution variance also depends on scale. The results demonstrate that the zoning effect should not be ignored, and the sensitivity of ecological analysis results to the analysis zones should be assessed. 相似文献

ABSTRACT Water, in all its physical, symbolic and metaphorical guises, has an obvious interconnection with people. Without water, human and other life forms cannot (and do not) exist. Less obvious is water's potential as a site of anthropological investigation to explore attachments to place. Such attachments, as Arturo Escobar observes, facilitate a multiplicity of place‐based cultures, and emerge when ‘connectivity, interactivity and positionality’ are present. His observation makes epistemological room for what Anna Tsing conceptualises as the ‘friction’ that permeates environmental and indigenous projects. Via Australian‐based Kimberley ethnographic insights, this article examines people's attachments to place‐based cultures when they become meaningful through multi‐layered tensions about water. 相似文献

In this article we examine the decisions made by the 85 United States representatives from the 13 states from which United States senators were retiring in 1996 and by the 137 representatives from states holding Senate elections in which incumbents were seeking reelection. We use these data to examine individual-level decision making in order to reassess the conventional wisdom on progressive ambition of House members. Using a decision calculus derived from previous studies, we are able to understand the decisions made by all but a handful of the representatives under study. These findings should prove useful in predicting which representatives will exhibit progressive ambition in the future. 相似文献

The World Food Programme (WFP) is currently the largest and arguably one of the most successful of the United Nations Special Agencies, yet there has been little examination of it by international relations scholars since the early 1990s. This article seeks to analyse the normative and political characteristics of the WFP which have contributed to its effectiveness. Among its most significant findings is that American agricultural interests, interpreted through the prism of domestic political norms, have dovetailed with ‘feed-the-hungry’ norms that are projected and implemented by the WFP, resulting in the strong support of the United States for the WFP. This support undermines the perception, promoted by some critics, that the UN is incapable of acting in ways that are compatible with the national interests of the United States and other significant member-states who inherently pursue ‘national interests’ in institutional environments. 相似文献

The site of A‘asu, American Samoa, is infamous in the annals of history as the site of a tragic encounter, in 1787, between
French explorers and Samoans, that left 42 or more dead and wounded. Beginning in 1876, an investigation of A‘asu was independently
conducted by a French missionary priest, Father Julien Vidal (SM). His letters document his search for answers at A‘asu, and
to find the resting places for the men left behind by the French fleet. Archaeological investigations at A‘asu carried out
in 2001 and 2002 yielded evidence that contribute to our understanding of the social transformations taking place in Tutuila
during the late 18th to early 20th century. 相似文献
