A programming approach is presented for identifying the form of the weights matrix W which either minimizes or maximizes the value of Moran's spatial autocorrelation statistic for a specified vector of data values. Both nonlinear and linear programming solutions are presented. The former are necessary when the sum of the links in W is unspecified while the latter can be used if this sum is fixed. The approach is illustrated using data examined in previous studies for two variables measured for the counties of Eire. While programming solutions involving different sets of constraints are derived, all yield solutions in which the number of nonzero elements in W is considerably smaller than that in W defined using the contiguity relationships between the counties. In graph theory terms, all of the Ws derived define multicomponent graphs. Other characteristics of the derived Ws are also presented.  相似文献

A reply by two North American geographers to the preceding article presents some recent results of North American studies and suggests that the role of water bodies in influencing cyclogenesis is not universal. The Black Sea is cited as an example of a large water body that does not act as a major source of cyclonic activity. Other arguments are presented questioning the significance of the large proglacial lakes in influencing storm tracks near the margin of the ice sheet.  相似文献

This paper incorporates a study of “re-ghettoization” among the Armenian Christians of the Islamic Republic of Iran. It focuses on how legal marginalization has led to the emergence of an entirely separate existence from the Muslim majority in Tehran among Armenians born after the revolution. By focusing on the spatial and social divisions of the hayashatner (Armenian neighborhoods) and the “social” ghetto of the Ararat Compound, this article addresses the question: what are the social implications for religious discrimination in the Muslim Middle East? This paper is based on three extensive blocks of fieldwork carried out in Iran from 2010 to 2015.  相似文献

The search for the origins of syphilis has a long history in the medical and anthropological literatures. If we know more about the emergence of the pathogen that causes the disease in humans we will understand its evolution through time and space as well as shed light on its current state in living populations. Ancient DNA techniques used to isolate Treponema pallidum subsp. pallidum DNA from archaeological human specimens provide direct evidence of its existence in the past. However to date, only Kolman et al. (1999) have been successful in this endeavour, while other attempts have failed (e.g., Barnes and Thomas, 2006; Bouwman and Brown, 2005). Why has there been little success? This paper serves to compliment and add relevant information to Bouwman and Brown's and Barnes and Thomas' discussion concerning our inability to apply ancient DNA techniques to study venereal syphilis in past human populations.Our approach utilized 15 different human specimens from different geographies and different temporal periods: eight samples come from medically diagnosed individuals archived during the American Civil War period; six originate from the United Kingdom and predate 1492 with four of these samples having been previously analyzed by Bouwman and Brown and one sample comes from historic Canada. Human mitochondrial and amelogenin DNA, as well as several genes from the Treponema organism were analyzed revealing the relatively good preservation of human multi-copy and single copy DNA but not treponemal DNA. This study also incorporates a unique molecular experiment using rabbits infected with venereal syphilis to help illustrate that treponemal DNA disseminates to bone early during the first stages of infection but is not present in later stages of the disease using the techniques presented in this study.  相似文献
