This article develops the argument that a ‘knowledge economy,’ despite its cheerful optimism, is also an elegant incarnation of the demise of Western economies. An analysis of policy documents, research statements, and national accounts reveals this paradoxical coexistence of anxiety and progress in the discourse on knowledge economies. While the concept is often hailed as a temporal concept (superseding other forms of economic production), this article argues that a knowledge economy is best understood as a spatial concept – it is a way of contending with global reorganizations of production. This spatial approach is elaborated to tackle three paradoxes. (1) A knowledge economy enfolds defeat with progress. (2) A knowledge economy downplays the importance of industrial labor and simultaneously depends on it to materialize its ideas. (3) While seemingly intangible and ephemeral, a knowledge economy is fixed in place in national economies through government and corporate policy (including through the emergent phenomenon of ‘knowledge-adjusted gross domestic products’). A spatial approach provides a view of the tenuous global interconnections and specific conditions that prop up a knowledge economy, and shows how the concept is mobilized to redraw the map so that endangered economies can regain their challenged sense of centrality in a world economy. 相似文献

Stone consolidation is one of the major restoration treatments used for historical monuments preservation. A natural stone is a complicated heterogeneous porous system making the process of consolidation dependent on many variables. In practical restoration aims, for a given stone type, the selection of a suitable consolidant and consolidation conditions therefore remains a complex issue. The impregnation depth is a key factor for the assessment of the treatment efficiency. The combination of state-of-the-art hybrid pixel semiconductor detectors with newly available micro-focus X-ray sources makes possible to apply X-ray radiography, an ideal non-destructive tool, for penetration depth monitoring. In this study, high-resolution X-ray radiography is used for monitoring the penetration depth of organosilicon consolidants in the Opuka stone. The penetration depth has been evaluated in relation to the time of consolidation, stone porosity and consolidation mixtures properties. The exact influence of the X-ray contrast agent on the consolidation depth has been investigated as well. The information obtained provides supplementary knowledge on the suitability of investigated products for the treatment of this type of stone. In our study, the capabilities of X-ray radiography have been demonstrated on X-ray radiography simple projections, high-resolution computed tomography (CT) as well as on the dynamic processes monitoring. The results thus can serve also as an instrumental and methodological example applicable for consolidation monitoring of other stone types. 相似文献

Earthquake relic is a unique geoheritage. At present, the research on earthquake relic geoparks or national parks is less domestic and overseas, while the protection, development and exploration are in its infancy. This paper, taking ‘Qingchuan Earthquake Relic Geopark’ (QERG) as an example, analyses the characteristics of the geopark, and explores the development model, in order to provide reference for the earthquake relic geopark and national park development domestic and overseas. 相似文献

Historic buildings are important for cultural history and provide a variety of habitats for animals and plants. Especially structural heterogeneity of wall surfaces is perceived to support biological diversity. Nevertheless, in traditional approaches goals of biodiversity preservation and monument restoration are perceived to interfere and to be mutually exclusive. As a consequence, priority is often given to constructional restoration accepting the loss of local populations and biodiversity. At walls of medieval castles, including an experimental restoration project where conventional and less intensive restoration techniques were applied, we relate species composition and richness to wall properties. Especially wall surface structure is quantified using a novel approach. The study focuses on lichens, mosses and vascular plants. Boosted regression tree analyses and non-metric multidimensional scaling techniques are applied to detect the influence of abiotic site conditions on biodiversity. We find species richness to be promoted by wall surface heterogeneity. However, species composition is more affected by restoration approaches than species richness. Lichen composition varies considerably while vascular plants and mosses are less affected by wall properties. We suggest strategies that are combining both societal targets, the preservation of historic monuments and of species diversity. Careful restoration is capable of supporting both, the maintenance of cultural heritage and of rare and unique anthropogenic habitats. Wall surface heterogeneity needs to be witnessed for both aspects as it affects both species composition as well as the effectiveness of cleaning methods. 相似文献

Systematic interventions are being planned and progressively designed on most buildings of the Arsenale of Venice, the Venetian republic’s shipyard, a very large complex of docks and sheds of peculiar construction characteristics. These renovation interventions are required in view of new uses for the revitalizing of that area, which is currently almost completely neglected. In the paper, after a general presentation of the main properties and of the most relevant deterioration phenomena of the principal parts of the monumental area, the methodology that is being used for the structural diagnosis, for the implementation of guidelines for the future interventions and for the maintenance of the restored conditions are presented. Some preliminary results, given by experimental tests performed both in situ and in laboratory on materials and structural elements, and by FE simulations, are discussed. 相似文献

Between 1939 and 1959, the regime led by General Franco pursued a policy of economic self-sufficiency. This policy inflicted great injury on Spanish science and industry, not least in Catalonia, and in its capital, Barcelona. In response, Catalan industry looked to a future made more promising by the advent of nuclear power. This paper describes the innovative role of an industrial body, the Official Chamber of Industry of Barcelona, in catalyzing one the first programmes of teaching and research in nuclear engineering in Spain. 相似文献

While originally Lacan seconds Heidegger's contention that ‘anxiety has no object’, in the early 1960s, he dismisses his own earlier position as a childish reassurance and argues, to the contrary, that ‘anxiety is not without an object’. With particular attention to his use of the double negative, ‘not without’, this essay examines this turning point in Lacan's thinking in order to explain the opposition between his psychoanalytic critical theory and Derrida's deconstruction. The arguments that Lacan brings to bear on his work of the 1950s closely approximate those that Derrida levels against Heidegger in the formulation of his own concept of ‘the aporia of the impossible’. Indeed, as commentators often emphasise, the formal logic of Lacan's later thinking is strictly isomorphic with Derrida's philosophy; and their respective concepts of anxiety and aporia are frequently misconstrued, accordingly, as simply identical. However, insofar as Lacan discerns a content in this formal negativity, contesting the idealism of his earlier theory and reasserting the materialist objectivity of the Freudian ‘lost object,’ as intractably Real, the two do not coincide. On the contrary, Lacan's repudiation of Heidegger's concept of anxiety extends equally to Derrida's aporia, as if, for Derrida, Heidegger's existential phenomenology were not reassuring enough. 相似文献

The archaeological site Pinara, southwest Turkey, which includes several remarkable objects of cultural heritage, has been the focus of several previous archaeoseismic studies. One of these examined the setting of the Roman theater in the east of Pinara by a lidar survey. A gross inclination of the stone rows of the auditorium of 0.81° towards N 314°E was interpreted as a consequence of recent coseismic tectonic movements. A new survey of the theater with a terrestrial phase laser scanner is the basis for a model with 15 times higher resolution and 28 times more data points. Parallel to the fieldwork in this study, the process and accuracy of the leveling of the 3D point clouds produced by the scanner was tested in a series of experiments. Based on the orientation of the blocks forming the seats of the theater, we suggest six sections with changing average inclination of the seats and a fault line separating a northern and a southern section. While the previously found overall inclination of the auditorium is confirmed by the new model and the dip direction agrees, the inclination is 0.58° compared to previously determined 0.81°. The almost perfect increase of inclination with the height of the first 10 entire seating rows and the nearly constant inclination from row 11 onward, makes systematic measurement errors during the construction a possible cause. This is an alternative scenario to the interpretation of a coseismic displacement of the conglomerate block on which the theater was built. 相似文献

This paper employs logistic regression to explore the relationship between art lessons and art history and appreciation classes as a child with adult visits to art museums. The regression-based technique allows for control of other influences such as demographic indicators of tastes and preferences. The results are generally consistent with the hypothesis that early exposure results in later participation, although exposure seems to have strongest influence in the pre- and post-teen years. 相似文献

Many people argue that public art contains an element of bequest value: value derived by people today from the expected enjoyment of the art by future generations. In this paper, I investigate the existence of this claimed benefit. I employ an intergenerational model of the benefits from government subsidies and private charitable gifts to the arts, and fit it empirically using 1996 US General Social Survey data. The data analysis suggests that people take their life expectancies into account to some extent when giving to the arts or supporting government arts spending. Indeed, we cannot reject the hypothesis that people do not consider future generations in their current support for the arts. 相似文献

A simple sol-gel technique for the preparation of methyl–modified silica coatings for the protection of the external surface of copper has been used in this study. Tetraethylorthosilicate (TEOS) has been used as a precursor to prepare nanosilica coatings on the surface of copper. The methyl–modified silica sols were obtained by mixing of 3% SiO2 sol solution with trimethylchlorosilane (TMCS) or hexamethyldisilozane (HMDS) as basic materials. For comparison, the copper substrates were also coated with commercial polymers (Paraloid B 72, Plexisol P 550-40 and polyvinyl butyral (PVB)). The surface morphology changes of uncoated and coated specimens were investigated by atomic force microscopy (AFM) and scanning electron microscopy (SEM). The hydrophobicity of surfaces and photochemical ageing effects were evaluated by contact angle measurements. Potentiodynamic measurements were obtained in order to compare corrosion parameters of the coatings. 相似文献
