In 2022, an Athenian red-figured cup attributed to Makron was returned to Italy by New York’s Metropolitan Museum of Art. The cup had been acquired in fragments, through purchase and gift, from multiple sources over several years, starting with two fragments from the restorer Fritz Bürki in 1978. A second cup, also attributed to Makron, was acquired in a parallel way. The sources for the fragments from both cups point to galleries collectors and donors – Summa Galleries, Frieda Tchachos, Elizabeth Hecht, and Dietrich von Bothmer – who have been associated with other material that has been repatriated to Italy in recent years. It is suggested that some of the incised ‘signatures’ by Hieron that are found on cups attributed to Makron may have been applied since antiquity. 相似文献

"The spread of HIV-1 in the United Kingdom is simulated by a model which integrates behavioural and epidemiological processes within a multi-regional population projection framework and represents the spatial heterogeneities in the distribution of HIV which have significant effects on transmission patterns. Analyses determine the significance of different parameters in contributing to prediction uncertainty and highlight the importance of behavioural change and international population movements." 相似文献

The author presents an approach to the analysis of labor migration that incorporates the role of market wage variability as a source of information in individual migration decisions. "The focus...is on quantifying the effects of the origin market acting through amenities and the share of market-specific wage variability as it affects forecasts of alternative wages and forecast precision. A subsample of employed males...from the [U.S.] National Longitudinal Survey of Youth (NLS) age 16 to 22 years is used for estimation. The empirical results are consistent with the theoretically predicted relationship between migration propensities and regional differences in the information content of wages. In addition, the results provide evidence that risk aversion deters migration given uncertainty, measured by forecast precision, about alternative market wage levels." 相似文献
