ABSTRACT

In the mid-eighteenth century music underwent a sudden and drastic revolution when composers “discovered” a new dimension to their art. This had immense repercussions on the philosophy of art, for the music created before and after this divide represents two different species of aesthetic experience, which in due course affected our understanding of the meaning and import of the other arts as well. Despite the immense aesthetic repercussions of this Copernican revolution in music, philosophers of art seem not to have taken much notice of it. This essay details the emergence of the relevant musical criteria during the eighteenth century and dwells on their long-term impacts on the philosophy of art.  相似文献

The study analysed pre-Hispanic gold objects found within a surprising archaeological finding of a structure that likely served as a funeral pyre in Medellín, Colombia. 14C analyses of the site's organic materials dated the structure to the fifth century ce . The metal objects were subjected to X-ray diffraction (XRD), energy-dispersive X-ray fluorescence (EDXRF), scanning electron microscopy-energy dispersive X-ray (SEM-EDX), density measurement by the Archimedes method, and metallographic analysis. The measurements by EDXRF and SEM-EDX showed that the pieces were composed mostly gold and silver. The XRD results indicated that the microstructure of the objects corresponded to a single phase of gold and silver. The images obtained by the metallographic microscope showed equiaxial grains with some twins, a structure consistent with annealed metals. The different colours observed correspond to different grain orientations. Pre-Hispanic objects from a second archaeological site in the municipality of Amalfi (Department of Antioquia) were also analysed for comparative purposes. The results showed that the gold objects were not subjected to any alloying process, but were instead manipulated in their original form (native gold). The shape of the objects and their microstructural results suggested that the pieces were manufactured by casting, mechanical deformation and then annealing.  相似文献

Five unidentifiable, completely corroded ancient coins (three of which were large fragments), proven to lack any residual internal metal, were scanned by nano-computed tomography (CT) to see if discernible detail might still be present. One fragment could be identified as an early fourth-century Urbs Roma commemorative AE 3/4. Another fragment was a coin of either Valerian or of the joint rule of Valerian and Gallienus, which could be dated to the period 254–56 ce . The other three lacked discernible detail. This proof-of-concept study shows that nano-CT scanning has the potential to allow non-invasive identification of at least some totally corroded coins.  相似文献

The study analyses the chemical composition of 57 glass samples from 40 beads discovered at 20 archaeological sites in Poland. The beads are dated to Hallstatt C–Early La Tène periods (c.800/750–260/250 bce ). Analyses were carried out using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). Two groups were distinguished among the glasses based on the MgO/K2O ratio: high-magnesium glass (HMG), five samples; and low-magnesium glass (LMG), 52 samples. The former were melted with halophyte plant ash, the second with mineral soda. These glasses were produced in the Eastern Mediterranean (more likely in Mesopotamia or Syro-Palestine than in Egypt) and transported in the form of semi-products to secondary glass workshops in Europe. Some of the white opaque glass was coloured and opacified in Europe.  相似文献

Across cities, one observes similarities in poverty and earnings of individuals within the same neighbourhood. Are these similarities due to causal influences neighbours exercise upon each other or to spatial sorting? We analyse this within the frame of a fixed effects model, estimated on a register-based panel covering all residents of two urban areas in Norway over the years from 1997 to 2011. We find a significant depressing effect of the share of low-earners in the neighbourhood on individual earnings in the capital region - Oslo. Our estimates of the impact of neighbourhood poverty are small in magnitude compared to what is found in other studies. In the other, less central area studied, we do not find any such effect. It is tempting to speculate that sorting and neighbourhood effects are less intense in urban regions with a smaller menu of neighbourhood choices.

In the ongoing coronavirus disease 2019 (COVID-19) crisis, uncertain and experimental forms of governance have emerged. Administrative routines and established management techniques have dissolved amid emergency actions and management by the state of exception. We refer to these emerging governance forms as transformative governance. Discussing examples from Switzerland, we illustrate how policy responses to COVID-19 reflect transformative governance. These examples raise four issues that characterize transformative governance research and practice: (i) the evidence base of policy-making; (ii) the role of the state in transformative governance; (iii) the potential of experimental governance; and (iv) the paradigms driving policy change. Our study demonstrates that these issues imply different opportunities and risks of transformative governance, which we discuss in detail.  相似文献
