This study uses service area–based coverage and various count regression methods to assess neighbourhood-level healthy and unhealthy food environments, and food access associated with different socio-economic groups in Edmonton, Canada. We identify three types of vulnerable neighbourhoods according to different food environments: food deserts (i.e., neighbourhoods lack sufficient access to healthy foods); food swamps (i.e., neighbourhoods have excess access to unhealthy foods); and those with overlaps of food swamps and food deserts. We also identify neighbourhoods with superior access to healthy foods (i.e., food oases). Additionally, our results from regression analyses indicate: (1) child population is negatively associated with both healthy and unhealthy food resources; (2) good access to public transportation is associated with good coverage of all healthy food outlets and convenience stores; and (3) deprived neighbourhoods with higher percentages of minority populations have better coverage of both healthy and unhealthy foods in general. The results from this study can help the City of Edmonton identify the key neighbourhoods with high potential for local business and the hotspot neighbourhoods that require particular support. Tailored strategies are proposed to effectively and efficiently improve food environments with limited resources.  相似文献

This article offers a critical account of Spanish high-speed rail (HSR) through the lens of the spatial fix. I designate the integration of Spanish HSR into a European-wide process of circulation of finance capital as the HSR-finance complex. The analysis of the inner workings of the HSR-finance complex reveals the way in which European finance has laid the conditions of possibility for the development of the project and offers a forewarning about the dangers of leveraging finance capital toward green infrastructure. The analysis of the Spanish HSR-finance complex shows that the particular form of capital circulation that has made it possible has not brought about new productive combinations but has instead deepened traditional relations of economic dependency and magnified their socioenvironmental consequences.  相似文献

ABSTRACT

Scholars have long debated the place in medieval historiography of Jean d’Outremeuse's Myreur des histors, a universal history in celebration of Liège written in French around 1399. The abundance of Old French epic material in a chronicle that, according to its author, contained translations of only Latin sources, was once a source of outrage. The Myreur now holds significant interest, however, for its evidence of late medieval narrative strategies. This study demonstrates the Myreur's deliberate adaptation of epic material to glorify Liège. The author reimagines the Carolingian past as a source for future historical narratives by knowingly altering the genealogical framework of the chanson de geste universe. Carrying tales of sexual impurity, he describes the demise of the Carolingian line and transforms figures from epic to function within his linear history. This inventive approach allowed him to create a new hero- and history-generating lineage for his universal history.  相似文献

ABSTRACT

The Imperial Academy of Medicine of Paris met in the spring of 1865 to discuss the localization of speech. One of the participants was Maximien Parchappe (1800–1866), an alienist whose research interests lay in the cerebral cortex. This article addresses Maximien Parchappe’s concept that the cognitive elements of language—such as the translation of thoughts into words, the will to express them, and the means to do so—reside within the cortical gray matter, and that they are integrated through white-matter fibers. In so doing, Parchappe anticipated Carl Wernicke’s linking of the posterior aspects of the dominant frontal and temporal lobes in verbal expression, and Jules Dejerine’s linking of the angular gyrus and Wernicke’s area in the understanding of written language. Functional imaging has revived interest in language as a network of neuronal aggregates and has given new relevance to Parchappe’s concept of the functional organization of language.  相似文献

Infants of Aragon are very important figures in the history and literature of the nineteenth century, but it is rare that one of them, Don Enrique, is the protagonist. This work analyzes the romantic story Cronica. Año de 1420, published by Jerónimo de la Escosura in 1839. In it, Enrique de Aragón is a cunning courtier and a poet in love, and he manages to change history because he changes the story with his verses.  相似文献
