This study discusses the importance of balancing spatial and non-spatial variation in spatial regression modeling. Unlike spatially varying coefficients (SVC) modeling, which is popular in spatial statistics, non-spatially varying coefficients (NVC) modeling has largely been unexplored in spatial fields. Nevertheless, as we will explain, consideration of non-spatial variation is needed not only to improve model accuracy but also to reduce spurious correlation among varying coefficients, which is a major problem in SVC modeling. We consider a Moran eigenvector approach modeling spatially and non-spatially varying coefficients (S&NVC). A Monte Carlo simulation experiment comparing our S&NVC model with existing SVC models suggests both modeling accuracy and computational efficiency for our approach. Beyond that, somewhat surprisingly, our approach identifies true and spurious correlations among coefficients nearly perfectly, even when usual SVC models suffer from severe spurious correlations. It implies that S&NVC model should be used even when the analysis purpose is modeling SVCs. Finally, our S&NVC model is employed to analyze a residential land price data set. Its results suggest existence of both spatial and non-spatial variation in regression coefficients in practice. The S&NVC model is now implemented in the R package spmoran.  相似文献

Unjustifiably, but often, dismissed as the driest of sources, medieval accounts can be a mine of historical and social information, and those of Isabeau of Bavaria, queen of Charles VI of France, are particularly fascinating. One of the many consequences of the king's lifelong mental instability was the development of an entirely separate financial administration for his wife and children, and this combination of radical innovation and unprecedented levels of expenditure has meant that scrutiny of Isabeau's accounts — the best preserved and most extensive of any medieval queen of France — has been considered fundamental in almost all biographical works. Although this paper looks at what could be regarded as a frivolous topic in Isabeau's wardrobe, the social concept of the royal lady as decorative fashion-plate has been particularly pertinent in recent years, but also has a long-standing pedigree. The necessity and public display of wealth were always an intrinsic element of medieval queenship, and a number of these wider themes will be explored alongside detailed analysis of two example accounts.  相似文献

The economic downturn in Indonesia (1997‐99) has changed the context of gendered spatial mobility in South Sulawesi. For low-income migrants in the region, the monetary crisis has not only reorganized the labor market, but it has also brought about an intensification of the stigma placed on young women's independent residence in an export processing zone. Household surveys and in-depth interviews with migrants and members of their origin and destination site neighborhoods, both before and during the economic retrenchment, illustrate that ideas about women's sexual morality are a key part of the context within which migration decisions are gendered. The article situates survey and interview findings within an overview of Indonesia's recent development history, economic crisis, and official state gender ideology. The article argues that migrants and their communities have identified the ‘prostitute’ as a female-gendered metaphor for the crisis, and finds that post-1997 narratives of women's mobility increasingly revolve around normative judgements regarding young women's independent mobility and sexual behavior.  相似文献

Central to both the causes and development of the English revolution was the demand for reformation of the Church of England. The question of what shape this reform should take, however, divided English men and women. Debates over the further reformation of the Church of England were also complicated by the emergence of increasingly vocal and powerfully‐placed calls for freedom of religion, ranging from a limited toleration for a certain few to a broader liberty of conscience for all. This article looks at the debate surrounding liberty of conscience during the English revolution in 1644–5, but from a fresh angle: examining the context and rationale for the parliamentary ordered religious settlement of the English Atlantic colony of Bermuda in October of 1645. Integrating the fortunes of this Atlantic colony into the history of the English revolution reconfigures our understanding and analysis of revolutionary religion and politics.  相似文献

This paper explores the relation of fear to activism in private and constrained circumstances of chronic risk and anxiety. Asking how people contest domestic violence, given the intensity of the fear that it generates, the paper reframes their responses as practices of activism. It draws on qualitative research that charts the nature, experience and effects of fear over time. Using seismology as a metaphor for this process, the analysis describes complex and often hidden shifts in emotions over periods of years, as interviewees describe being simultaneously constrained by fear and actively using fear to manage and contest violence. Their practices of resistance are small scale, largely invisible to others, and have a messy and non-linear relationship with the process of leaving that some eventually undertake. Such action is only necessary in a social and political climate which continues to place more emphasis on individual than social responsibility for domestic violence. I examine what this resistance adds to recent accounts of activism, concluding that isolated actions constitute activism when they anticipate or engender collective social and political change at other scales.  相似文献

Eigenvector spatial filtering (ESF) is a spatial modeling approach, which has been applied in urban and regional studies, ecological studies, and so on. However, it is computationally demanding, and may not be suitable for large data modeling. The objective of this study is developing fast ESF and random effects ESF (RE‐ESF), which are capable of handling very large samples. To achieve it, we accelerate eigen‐decomposition and parameter estimation, which make ESF and RE‐ESF slow. The former is accelerated by utilizing the Nyström extension, whereas the latter is by small matrix tricks. The resulting fast ESF and fast RE‐ESF are compared with nonapproximated ESF and RE‐ESF in Monte Carlo simulation experiments. The result shows that, while ESF and RE‐ESF are slow for several thousand samples, fast ESF and RE‐ESF require only several seconds for the samples. It is also suggested that the proposed approaches effectively remove positive spatial dependence in the residuals with very small approximation errors when the number of eigenvectors considered is 200 or more. Note that these approaches cannot deal with negative spatial dependence. The proposed approaches are implemented in an R package “spmoran.”  相似文献

This article investigates the “bureaucratic capture” of migrant children through three technologies of the state: labelling, data production and social services, illuminating the ways visibility and invisibility are constructed and managed in the context of restrictionist immigration regimes. Using the case of unaccompanied asylum‐seeking children, Roma children and undocumented children, we examine how in/visibility is produced; for what purposes, and with what consequences. We demonstrate through the simultaneous broadcasting and disappearance of migrant children, bordering is reconstituted through various performances, rationalities and technologies of immigration governance. The article argues the notion of “best interests” is drawn on when the state can define these interests in accordance with their political aims and resources. The set of cases taken together provide novel insights into how states reconcile conflicting logics and reveals how the implementation of the child rights regime prevents some children from actualising their rights.  相似文献

The literature is replete with acknowledgments that spatial autocorrelation (SA) inflates the variance of a random variable (RV), and that it also may alter other RV distributional properties. In most studies, impacts of SA have been examined only for the three most commonly used distributions: the normal, Poisson (and its negative binomial counterpart), and binomial distributions; much less is known about its effects on two other RVs that are utilized in GIScience research: the beta and the multinomial. The beta distribution—which is considered to be very flexible because it can mimic a uniform, exponential, sinusoidal, and normal RV—can be utilized to analyze the radiance of a remotely sensed image, for example. The multinomial distribution, a generalization of the binomial distribution, has been widely used for land use classification, and to describe land use change. The literature also suggests that RV impacts of negative SA, a neglected topic in spatial analysis, may differ from those of positive SA, at least for some RVs (e.g., the Poisson RV). The purpose of this article is to extend the investigation of effects of SA to beta and multinomial RVs, with both positive SA and negative SA assessed and contrasted with each other, using simulation experiments. The simulation experiments are designed to support this assessment. One of the major discoveries is that impacts of positive SA and negative SA behave similarly when a RV conforms to a normal distribution; however, maximum negative SA is unable to materialize for asymmetric RV, whereas positive SA always converges upon its maximum.  相似文献
