Historical preservation often reveals more about contemporary culture than about history. The Alamo in San Antonio, Texas, is just such a case. No other large US city is so dominated by a single historical event, and the Alamo plays a central role as a cultural icon for regional Anglo identity, a symbol of the Anglo-dominated social hierarchy. Its preservation and restoration have coincided with modern identity formation contextualized by commodities. Thus, a critical part of this project is the development of a consumer landscape as an economic extension of the Alamo that promotes consumption by harmonizing with prevailing Anglo conceptions of ethnic identities; not simply a strategically located commercial zone, but an integral part of the pilgrimage to the monument, providing a mechanism for socialization, including "racialization", contextualized by commodities.  相似文献

A substantial problem in studying the geographical epidemiology of rare noncontagious diseases is to estimate the risks of their development within populations. A geostatistical solution is described and illustrated by a case study of cancer among children in the West Midlands of England for the years 1980 to 1984 inclusive. Data consist of the numbers of diagnosed cases of cancer and of healthy children in each of 838 electoral wards, the centroids of which are known accurately. The rate of incidence or frequency, equal to the number of cases divided by the number of children, is a binomial variable and is treated as a realization of the underlying risk of a child's developing the disease that varies from place to place. The experimental variogram of the frequency was computed using the standard formulation. The variogram of the risk was obtained from it taking into account the numbers of children at risk and the error associated with each observed frequency. The variogram of the risk increased monotonically from 0 at zero lag to about 50 kilometers, and it was modeled as Whittle's two-dimensional elementary correlation function. The covariances of frequency and cross-covariances between the frequency and the risk were derived from it, and these were then used together with the data to krige the risk and map it. The risk of developing the disease is shown to have a patchy distribution, strongly autocorrelated at the regional scale of the investigation.  相似文献

The “field trip” is a key pedagogical tool within geographical education to encourage deep learning, though they are increasingly difficult to implement due to reduced budgets, safety concerns and increasing class sizes. We incorporated three field-learning activities into a large introductory module. A traditional staff-led trip was the most effective activity in terms of enjoyment, knowledge, and deep thinking and awareness. Self-paced field activities and video podcasts had less pedagogical value, though can still support lectures and the staff-led field trip. An integrated approach will best maximize deep learning opportunities.  相似文献

Chemical analysis of residue extracted from stone pipes and pipe fragments excavated at sites in the southern Pacific Northwest Coast of North America demonstrate that hunter-gatherers smoked the psychostimulant tobacco (Nicotiana sp.) by at least AD 860. Non-farming ethno-historic Native Americans throughout the west gathered and sometimes cultivated tobacco for ritual and religious purposes, but until now the antiquity of the practice on this part of the continent was unknown. Method validation includes chemical characterization of a suite of smoke plants and experimental reproduction of “smoked” pipe chemistry; results indicate biomarkers are traceable for several species commonly smoked by ethnographic native peoples, including tobacco (nicotine, cotinine), tree tobacco (anabasine), and kinnikinnick (arbutin). Developed methods—where residue is extracted directly from the stone or clay matrix of whole and fragmentary archaeological pipes—may be applied in similar studies investigating the spread and use of ritual smoke plants in the ancient Americas and elsewhere.  相似文献

Comparison of mass transfer patterns, geometry and microstructures developed within and around veins allows the interpretation of processes of fluid flow during deformation, metamorphism and mineralization. A classification of vein types based on the degree of interaction with wallrock (using petrological, geochemical or isotopic indicators) can be used to identify a range of processes, from closed system behaviour in which the vein mass is derived from local wallrock, through to open system behaviour in which the vein mass is derived externally. Microstructural characteristics, such as wallrock selvages, multiple growth events recorded by vein seams and vein crystal morphology, also help to constrain mass transfer patterns during vein formation. We present a range of processes for vein formation, including: (i) the formation of closed system fibrous veins by dissolution–precipitation creep, including varieties in which tensile failure is not required; (ii) pressure‐ or kinetically dependent closed system segregation veins in which transfer of soluble components from wallrock to vein leaves behind a residual selvage; (iii) similar vein–selvage patterning, but with mass imbalances between vein and wallrock requiring fluid advection through both interconnected fracture networks and in the surrounding permeable rock; and (iv) the proposed formation of veins by fluid ascent in mobile hydrofractures, in which isotopic or chemical disequilibrium within and around the vein suggests that the crack and fluid within it moved essentially as one. The postulate of rapid fluid and mass transfer via such mobile hydrofractures has implications for the release of volatiles from metamorphic terrains. Also, consideration of a broad range of possible vein‐forming mechanisms is highly desirable when dealing with mineral deposits found in deformed, metamorphosed rocks, because closed system veining may produce patterns that, if erroneously recognized as being open systems, could lead to false interpretations of the role of tectonic fracturing in ore genesis.  相似文献

The consideration of psychoanalytic issues presents geography and geographers with a number of difficulties; this paper examines those difficulties from within a humanistic perspective. The most common geographical engagements with the psychological therapies have been with their psychodynamic and, to a lesser extent, humanist methodological forms. A humanist perspective on this engagement suggests that it has led to two associated problems. At a disciplinary level it has resulted in an approach that has tended to privilege intellectual knowledge at the expense of emotion, and at a personal level it has not encouraged an approach that is sensitive to difference. This essay proposes that a commitment to an engaged, 'congruent' listening might help temper these difficulties.  相似文献

For a total of twenty years (1856–76), Gustave Flaubert corresponded with a woman whom he would never meet and who had first written to him to express her admiration for his novel, Madame Bovary. These forty-five letters are among the most fascinating and important that he was to write, reflecting on his life, on art and esthetics, and on his determined dedication to the practice of writing. The letters to Marie-Sophie Leroyer de Chantepie occupy a central role in Flaubert's Correspondence, between the long series of letters he wrote to two other women, Louise Colet and George Sand. They are all dominated by the idea of the centrality of art, literature, and the activity of writing, and of the subordinate status of all other experiences and interests.  相似文献

The modern popular cult of the Pope, which originated with the ‘disinherited’ papacy of Pius IX, reached its acme with Pius XII. Phases of intensification of this cult, which was linked to other ‘devotions’, those of the Sacred Heart of Jesus and of the Virgin Mary, served to mobilize the Catholic masses at critical junctures for the Catholic Church and in the face of what were perceived as political threats. Pius XII had to animate ‘movement’ in an age proclaimed to be one of a unique crisis of civilization. The projection of him as a charismatic figure was linked to that of Rome as a sacred centre and as the very fulcrum of world history. The Catholic activist ethos of ‘movement’ and also the presentation of the interchange between Pius XII and the Crowd had features in common with Fascist rhetorics, but ultimately the cult of the ‘victim‐Pope’ represented an inversion of the crasser forms of power‐imagery.  相似文献
