The style of the contemporary German artist Anselm Kiefer is highly innovative and unconventional and is characterized by the use of diverse materials that he selects and combines according to the emotions that they stir in him. The conservation and preservation of works by Kiefer are particularly difficult tasks because of the heterogeneity and, in some cases, the incompatibility of the materials used; therefore, a thorough characterization is crucial before any intervention is considered. In this paper, we report the results of an investigation on a fragment from a multimaterial work and on samples from the paintings Bohemia Lies by the Sea and Die Größe Fracht. The large fragment was cut by the artist himself from a work in progress and is considered destitute of any artistic value; therefore, it was possible to sample it extensively. This fragment and the samples from the Die Größe Fracht and Bohemia Lies by the Sea paintings were analyzed by ultraviolet (UV) fluorescence imaging, fiber optic reflectance spectroscopy, Fourier transform infrared spectroscopy, nuclear magnetic resonance, Raman spectroscopy, X-ray diffraction, gas chromatography-mass spectrometry, and pyrolysis gas chromatography-mass spectrometry. This multitechnique approach allowed us to fully characterize and identify pigments, dyes, and organic components that reflect the diversity of the materials typically chosen by the artist. The results are evaluated in the context of the interview that Antonio Rava had with the Anselm Kiefer in 2000.  相似文献

The article analyses social discourses about the Internet in Italy from the mid-1990s onwards, taking its examples from advertising. Beyond the individual campaigns and their subjects there have been two distinct trends in Internet advertising. The first has made an effort to build the Internet as a cognitive object, the second has presented the Internet as a 'possible world'. The article aims to account for the ways in which the Web has been thematized in Italy: its fields of reference, and how its possible social and personal uses have been anticipated.  相似文献

This study examines the relationship between an entrepreneur's absorptive capacity, the spiral of knowledge and local development. Although a great number of theoretical and empirical studies have pointed out the importance of local networking and informal contacts when spreading knowledge locally, very few of them have provided robust evidence on the role of the entrepreneur's absorptive capacity and external knowledge in local development. This paper tries to explain the reasons why this problem can no longer be ignored and provides a preliminary examination, through an exploratory case study, of the role that the entrepreneur's absorptive capacity and external knowledge play in overcoming territorial inertia and enhancing local development.  相似文献

The influence of local geology and soil conditions on the intensity and the amplification of ground shaking are well known. Part of the old city center of Trieste is built on the site of a former salina, placed at a river mouth and is characterized by soft sediments several tens of meters thick. A new accelerometric station has been recently installed in a historical building, in order to analyse earthquake-induced site amplifications. This station has recorded five regional earthquakes and the related records are compared to those obtained at a nearby bedrock-installed accelerometeric station. Fourier and response spectra for all components are computed and both the H/V ratio and the reference station techniques are used to assess site effects. Noise measurements performed in the historical building, where the accelerometer is located, confirm these results. Relevant amplifications are detected in the frequency range of 2–4 Hz, particularly important for the type of buildings present in this part of the city.  相似文献

Scholars have recently paid more attention to narratives of colonial contact in Australia, as elsewhere (cf. Hill 1988). Western elements and characters (such as Captain Cook) have been widely documented in Australian Aboriginal narratives which nevertheless are clearly not close accounts of past events. This has promoted reconsideration of the distinction between ‘myth’ and ‘history‘. If we follow Turner's (1988) suggestion that myth is the formulation of ‘essential’ properties of social experience in terms of ‘generic events‘, while ‘history’ is concerned with the level of ‘particular relations among particular events’, we need not restrict ourselves to seeing myth as charter for a social order distinct from western influence. In the paper I examine two stories of cultural and physical survival from the Katherine area, Northern Territory, and seek to identify in them fundamental themes and enduring narrative precipitates of social experience lived in intense awareness of colonial and post-colonial relationships between Aborigines and whites.  相似文献

This study outlines the circulation of Phoenician–Punic amphorae in northern coastal Etruria, with a particular focus on Pisa (Italy), where their presence has been attested since the mid-eighth century BCE. A set of specimens from Piazza del Duomo was analysed by minero-petrographic and geochemical techniques. The results were compared with literature data from Mediterranean production areas. The research allowed a better definition of the role of Etruscan Pisa in the frame of commercial and cultural routes in the Mediterranean, specifically in the Tyrrhenian area, also providing the opportunity to review the attestations of Phoenician–Punic amphora on a regional scale.  相似文献
