In this article, we construct new, simple, and nonparametric tests for spatial independence using symbolic analysis. An important aspect is that the tests are free of a priori assumptions about the functional form of dependence, making them especially suitable in situations where the dependence is nonlinear. We define the concept of a similarity relation, which is used to keep track of similarity between neighboring observations. This similarity count is used to construct new statistical tests based on both random permutation simulations and derived asymptotic distributions. We include a Monte Carlo study to better illustrate the properties and the behavior of the new tests under several synthetically generated processes. Apart from being competitive compared with other nonparametric and parametric tests, results underline the outstanding power of the new tests for nonlinear‐dependent spatial processes. 相似文献

The process of colonial expansion in the sixteenth century fundamentally changed Spanish culture. Along with race, religion, ethnicity, status and honour, definitions of proper gendered and sexual behaviour changed as well. This article argues that Spanish communities and institutions came to define foreign men as examples of a subordinate and dangerous masculinity. The threat that foreign male sexuality posed to Spanish women and thus Spanish patriarchy – not only in the colonies, but within Spain itself – led institutions to prosecute foreign men. This essay draws on the language used in Inquisition and ecclesiastical court cases against foreign men as well as in Spanish literature of the period. 相似文献

In 1973, while recovering copper cargo from a 20th‐century ship wrecked off the Ponta do Leme Velho on the south‐east side of Sal Island, Cape Verde, explosives revealed an earlier ship cargo with dozens of Portuguese faience plates and bowls, glass beads and metal objects, including buckles, ammunition and copper manillas. The assemblage, including the ceramics and a marked silver tastevin, provide a site date between 1680 and 1700. The research presented here is a result of collaboration between CPAS and the authors in 2008 to analyse this assemblage in the context of late 17th‐century maritime trade. 相似文献

Focusing on children's experience-driven cosmologies revealed through interviews and survey responses, this article seeks to analyse and interpret the way children explain their migration from the USA to Mexico within the context of increases in both voluntary and forced return migration of Mexicans since 2005. It draws from representative samples of students (aged 9–16) enrolled in both public and private schools in several Mexican states, which are complemented by data drawn from in-depth interviews that complicate the sociological typologies about migration, motives for migration, and returnees. The goals of this article are as follows: (a) to illuminate and value children's own narratives about their migration experiences and (b) to discuss the contribution of diverse and apparently contradictory micro-, meso-, and macro-level approaches in studying migrant children. 相似文献
