ABSTRACTGiovanni Freppa (1795–1870), a well-known antiquarian, was instrumental in propelling the Ginori maiolica firm to reinvent the technique of Renaissance lustreware. The so-called ‘Freppa Scandal’ resulted after he sold as authentic Renaissance pieces a number of plates made by Ginori. Freppa was also famous, or rather infamous, for his exploitation of the young sculptor Giovanni Bastianini, whose remarkable neo-Renaissance portrait busts were sometimes sold as authentic Renaissance works. The Louvre purchased for an enormous price a bust believed to be a Renaissance masterpiece; but it was actually executed by Bastianini in 1864 on commission from Freppa, resulting in ‘the Benivieni Affair’. But this article is not primarily intended to expand on Freppa’s transactions in the art world; rather, it highlights his activities in many other spheres, including a failed publishing project with Giacomo Leopardi, among other activities. Freppa was a more complex individual than indicated merely by the two above-mentioned scandals. 相似文献

A General Misspecification Test for Spatial Regression Models: Dependence, Heterogeneity, and Nonlinearity 总被引:3,自引:0,他引:3

There is an increasing awareness of the potentials of nonlinear modeling in regional science. This can be explained partly by the recognition of the limitations of conventional equilibrium models in complex situations, and also by the easy availability and accessibility of sophisticated computational techniques. Among the class of nonlinear models, dynamic variants based on, for example, chaos theory stand out as an interesting approach. However, the operational significance of such approaches is still rather limited and a rigorous statistical-econometric treatment of nonlinear dynamic modeling experiments is lacking. Against this background this paper is concerned with a methodological and empirical analysis of a general misspecification test for spatial regression models that is expected to have power against nonlinearity, spatial dependence, and heteroskedasticity. The paper seeks to break new research ground by linking the classical diagnostic tools developed in spatial econometrics to a misspecification test derived directly from chaos theory—the BDS test, developed by Brock, Dechert, and Scheinkman (1987). A spatial variant of the BDS test is introduced and applied in the context of two examples of spatial process models, one of which is concerned with the spatial distribution of regional investments in The Netherlands, the other with spatial crime patterns in Columbus, Ohio. 相似文献

The argali (Ovis ammon antiqua) assemblages from the Middle Pleistocene site of the Caune de l'Arago (Tautavel, southern France) were studied in terms of zooarchaeology and taphonomy. It is possible to discern palaeobiological information lost during fossilisation, as well as the palaeoethology of the bone collector, by the observation of taphonomic details preserved on the bone assemblages. The observations leave no doubt that both humans and carnivores were involved in the accumulation of argali carcasses in the cave. In some assemblages, the type of bones found in articulation and the gnawing marks observed are characteristic of carnivores. In other levels, the intense fracturing of the major limb bones in relation to their marrow content and mineral density, and butchering marks found on specimens in the earlier levels, are in favour of human accumulation, the modalities of which are discussed. The results suggest that the degree of carnivore activity seems to have been higher in levels M, N and O than in level F. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

In research to reconstruct the design of a small Dutch vessel of c . 1600, morphometric analysis of ship iconography proved very useful. Both uni-variate and multi-variate modes of statistical analysis, as used in this research, are described and discussed. Four classifications of three-masted, square-rigged Dutch sailing vessels—ships, jachts, large jachts and small jachts—were shown to be clearly distinguished types in the multi-variate data space. 相似文献

广州西汉南越王墓和徐州狮子山汉墓是我国汉代最重要和出土玉器数量最多的两个王侯级墓地,两墓出土的丝缕和金缕玉衣是当时南方和中原汉王朝最重要的墓葬玉器之一。通过上手观察、显微镜拍照并利用环境扫描电镜和漫反射红外光谱、拉曼光谱技术对广州南越王墓及徐州狮子山汉墓出土玉衣部分玉片的质材和加工工艺进行了观察测试和对比分析。结果显示,两地玉衣的玉料均主要为透闪石质,从现存玉衣颜色及玉质结构上看,徐州狮子山汉墓出土玉衣玉料来源单一且玉质明显好于南越王墓,南越王墓玉料具有多来源的特征,玉衣中的“假玉”可能来自粤西。从南越王墓玉衣片部分切割痕迹判断,南越王墓所使用的切割工具可能接近当时的最高水平,也可能存在中原交换来源的玉材,无法排除南越王墓玉衣全部或部分在当地制作的可能;南越王墓和徐州狮子山汉墓出土玉衣加工工艺特征明显不同,显示两地玉衣系由不同 “玉作”体系加工完成,汉代可能存在多个不同的玉作体系,工艺水平参差不齐。 相似文献

In input-output analysis there are two alternate possibilities between Leontief's mechanism (fixed technical coefficients) and Ghosh's mechanism (fixed allocation coefficients). Testing the long-term consistency of these mechanisms entails comparing input-output matrices over time. This paper challenges the value of proportional filters (separate comparisons of column and row coefficients) and introduces the biproportional filter that allows simultaneous comparison of column and rows. An application is proposed using French input-output tables for 1980 and 1993. The stability of column coefficients cannot be taken for granted and, generally, for any sector, both row and column coefficients are found to change simultaneously. 相似文献

This re‐evaluation of existing data on board games from the Near Eastern Bronze Age demonstrates their function as social lubricants in cross‐cultural interaction. Board games are situated theoretically as liminoid practices, which lie outside the bounds of normative social behaviour and allow for interaction across social boundaries. Utilizing double‐sided game boards, with an indigenous game on one side and a newly introduced game on the other, the games of senet, mehen and twenty squares provide evidence for social interactions. Cypriots had adopted Egyptian mehen and senet by the third millennium BC, and indigenized the games. This lies in contrast to the game of twenty squares, which had a particular role among elites in the Late Bronze Age interaction sphere. This anthropological discussion of evidence relating to gaming seeks to inspire further research on the role of board games in society. 相似文献
