As an expression of his immense power and standing, Earl Ranulf de Blundeville, sixth Earl of Chester (1181–1232) granted his own Magna Carta in Cheshire. Ranulfs subsequent building programme can be regarded as comparable architectural expression. This article aims to provide a fresh interpretation combining a variety of approaches as to how Ranulfs personal power is manifested in the medieval landscape of north-west England and North Wales. It is argued that Ranulfs relatively overlooked and yet close relationship with Llywelyn Fawr, or Llywelyn ap Iorwerth, Prince of Gwynedd (C. AD 1173–1240), sheds further light as to the purpose of the position of Beeston and Cricieth castles in their landscapes. This study has wider implications as to how archaeologists can discern manifestations of lordly power in the designs and landscape settings of medieval castles. While this topic has been widely discussed over the last three decades, it has been hitherto under-investigated in the north-west of England and North Wales where the dynamic allegiances between lords were key components in how power was expressed.  相似文献

Abstract

Observation of cause–effect patterns of change in coastal environments provides insights into vulnerable areas and supports prediction and adaptation to flooding and erosion. Historic and periodic (6–8 year intervals) imagery from the Landsat archive is used to investigate transformations in the Atlantic coast of two Scottish islands over the period 1989–2011. Supervised classification of spectrally normalized images followed by change detection and spatial analysis reveals the patterns of change and the location of the most dynamic coastal areas. Quantitative measures of recent shifts and movement rates of relevant coastal lines, such as the lower limit of land-based vegetation, are assessed with the Digital Shoreline Analysis System. While very low rates are indicated for horizontal changes in the position of the lower limit of land-based vegetation (0.3?m?y?1), specific areas have been subjected to high rates of coastal progradation as well as erosion (e.g. 2.5?m?y?1 at Stilligarry). Information derived from satellite data supports the characterization of geomorphologically dynamic coasts at regional scales. With a rich and open access archive of imagery, a commitment to continuity, and compatibility with the Earth observation missions of other space programs, the Landsat mission offers useful and otherwise unavailable data for monitoring of coastal areas.  相似文献

ABSTRACT This paper investigates the interplay between nativity and both homeownership and foreclosure in Miami‐Dade County, Florida at both the individual and community levels. We estimate the likelihood of individual‐level home ownership based on place of birth and year of entry to the U.S., and separately estimate community‐level foreclosures based on the demographic composition of neighborhoods. Results confirm previous work: all subgroups, except Cubans, are less likely to be homeowners than white, non‐Hispanics and only Cuban neighborhoods had foreclosure rates significantly lower than rates in white, non‐Hispanic neighborhoods. Nativity has a stronger effect on homeownership than on foreclosure levels.  相似文献

ABSTRACT

This paper is the result of extensive investigation of the archives of the Dundas family of Arniston, Midlothian. It uncovers significant roles played in the organization of David Watson and William Roy's Military Survey of Scotland (1747–1755) by successive generations of the Dundases and suggests that the introduction of Watson, an established military engineer, to the young civilian Roy, was facilitated by that family. The Dundases' patronage of the Military Survey encourages us to understand the project as a private-public partnership and supports contentions that Enlightenment mapping resulted from complex social networks straddling military and civilian life.  相似文献

Politicians with presidential ambitions will often solicit asympathetic journalist to write a flattering biography as apreliminary for the campaign. Authorized biographies tell thelife story from the politicians’ perspective, highlightingtheir assets, ignoring their defects, and blaming their opponents.Usually based on interviews, they appear either as first person\"as told to\" autobiographies or as third-person narratives inwhich the biographer paraphrases and supplements material gleanedfrom the  相似文献

It is often argued that the most commonly assumed visual mode in geopolitics is the objective and disembodied gaze of the master geopolitical tactician. This is a charge that has been levelled at both geopolitical figures such as national leaders, and at academics who write about historical and present‐day geopolitics. However, recent work has diversified the way in which formal, practical and popular geopolitical visions may be examined in critical geopolitical studies. Such work calls for greater attention to be paid to popular visual cultures and to geopolitical practice as a way of envisioning global space that is embodied and subjective.  相似文献

The exposure of children to environmental disamenities has emerged as a key policy concern in recent years, with some analysts and activists suggesting that minority children are disproportionately impacted. Utilizing a dataset that combines air toxics at the census tract level with school-based demographic and other information, this article indicates disparate exposures for students of color in California schools and suggests that there may be negative impacts on one measure of academic performance, even after controlling for other factors usually associated with test scores. Policy implications include a special focus on school remediation and strengthening overall efforts to reduce emissions \"hot spots.\"  相似文献

Both gentrification and street art are concerned with the conquest of urban space. Although historically, graffiti and street art have functioned to challenge the status quo, a growing appreciation for urban art unveils a far more collaborative attitude between some street artists and the elite. A familiar esthetic of gentrified terrains involves repurposing spaces that capture the urban experience. In some cities, urban redevelopment preserves original materials that capture that “urban feel” by highlighting exposed brick structures, rustic furnishings, industrial lofts, and urban art. In other cities, these styles are recreated consciously. This paper draws from in-depth interviews with street artists from Austin, Texas, one of the fastest growing urban landscapes in the U.S., to discuss street artists’ attitudes towards gentrification. Its examination of stories and personal narratives about gentrification shows the complexities of rapid urban expansion as perceived by Austin street artists, and concludes that street artists remain ambivalent towards gentrification. While street artists experience some negative effects resulting from gentrification, urban redevelopment also has another clear benefit for them: an expansion of their urban canvas. The growth of city space extends street artists’ creative playground, which advances the artists’ opportunities for paid work and exposure.  相似文献
